Introduction:

 

Calcgate is designed to run within the Matlab computing environment, and uses a mathematical transform that enables the user to perform integral calculus on a variety of equations with incredible speed and accuarcy. Calcgate stands for: CALCulus Geometric Area Transform Equation, hence ‘Calcgate’. Calcgate uses a mathematical transform method to calculate work, energy, and integral area for any polynominal series with an accuracy of sixteen decimal places, instantly. Calcgate can also perform integral calculus with a fourier series as input. This allows work, energy and also co-variant integral equations to be determined. The fourier series program, intended primarily as a simulation tool for determining work, energy, and integral area, is now accurate to sixteen decimal places with a given harmonic series input. Another version, that is also much faster (including the equivalent of more harmonics) using discrete values for the force and integral area vector component(s), along with linear and exponential interpolation, with accuracies of sixteen or more decimal places for any given equivalent harmonic series input, will be available in the future sometime. Using polynominal input, Calcgate can calculate work and energy, with the Energy program, polynominal equations with powers up to 21 instantly and accurate to sixteen decimal places. Calcgate can also perform integral calculus on non-invariant equations, using polynominal input, with the same speed and accuracy using the Area program, however, the differential can be a power of up to 23. The Energy program also includes an initial velocity input, and select initial velocity from last calculation feature allowing different polynominal functions to calculated in series. This would enable say, the work and energy to be determined for a triangle or sawtooth force function by performing two separate calculation(s) in series then adding the two energy values, using the display total energy menu option and again the results accurate to within sixteen decimal places. For example, using a force f(t) = t, and f(t) = -t + 1 (and using an initial velocity v(o) or select initial velocity from last calculation feature on the integration time input GUI), on intervals of 0 to 1 seconds calculates the work and energy of a triangle force on the limits of integration of 0 to 2 seconds. Or say, for example f(t) = t^2, and f(t) = -t + 1 (and using an initial velocity v(o) or select initial velocity from last calculation on the integration time input GUI), calculates the work and energy of a parabola and ramp, on the limits of integration 0 to 2 seconds, accurate to within sixteen decimal places by simply doing the calculation(s) in series and adding the results using the display total energy option on the main menu. Other interesting combinations using algebraic equations with polynomial series as input, and using the initial velocity v(o) can be used to determine work and energy for the vector components to within sixteen decimal places instantly. Applications for calculation could include heat energy due to friction in mechanical systems, maxwell’s equations, simulations of high energy physics, astrophysical forces, forces between the earth and moon, co-variant integral equations, and much more,

to create f(t), f(x), and mass variables –

 

if f(t) is such that:

 

f(t) = t^7+t^6+t^5+t^4+t^3+t^2+t^1+1

 

and f(x) is:

 

f(x)1 = t^1+1

f(x)2 = t^2

f(x)3 = t^3

f(x)4 = t^4

f(x)5 = t^5

f(x)6 = t^6

f(x)7 = t^7

 

then perform the following:

 

a = zeros(1,28) initializes f(t) matrix.

a(1,1:8) = 1 sets the coefficients equal to that of those for f(t) which has powers powers 0-7

b = zeros(7,28) initializes the f(x) force vector component matrix

b(: ,1:1) = 1 sets the coefficients equal to that of those for the powers of f(x) which has powers of 0-7, in rows 1 through 7

mass = 1, sets mass equal to a value of 1.

 

The preceeding procedures creates variables f(t) = a, f(x) = b, mass = 1.

 

Note how f(x)n = f(t), i.e., the sum of the vector components equals the force function f(t).

Now just save the variables a, b, and mass to a mat file in order to load them from within Calcgate.

F(x) could also be initialized with all variables in one row, instead of separate rows, by performing the following:

b = zeros(7,28), and then b(1,1:8) = 1 creates f(x)1 =  t^7+t^6+t^5+t^4+t^3+t^2+t^1+1 which is stored in row 1, instead of the vector components being stored in separate rows 1–7 as in the preceeding example.

If the coefficients for the powers of t are other than 1, then they can be set accordingly in each matrix for both force f(t) and f(x) vector components.

 

The maximum powers, in the Energy program for both f(t) and f(x) are each 21. The preceeding steps can be used to set up the f(t) and f(x) variables for the Area program as well. The maximum powers of t, in the Area program, for f(t) is 23, and for f(x) is 21.

 

 

 

The fourier series program requires sinusoidal input in magnitude and phase form.

For example to create a force function with two vector components f(x)1 and f(x)2,  perform the following:

a = zeros(501,2)

a(1,1) = 4

a(1,2) = 1e8

a(2,1) = 1

a(2,2) = 45*pi/180

a(501,1) = .1

a(501,2) = 10*pi/180

 

creates a force function having a fundamental frequency of 1e8 with a constant term of 4 where the magnitude and phase of the fundamental are 1 and 45 respectively. The last value is the 500th harmonic with magnitued and phase of .1 and 10 respectively.

 

To create f(x)1 vector component perform the following:

b = zeros(501,2)

b(1,1) = 4.

b(501,1) = .1

b(501,2) = 10*pi/180

 

creates a vector component of f(x)1 that has a constant term of 4 and 500th harmonic

with magnitude and phase of .1 and 10 degrees (expressed in terms of radians) respectively.

 

F(x)2 consisting of only the fundamental can be created as in following:

c = zeros(2,2)

c(2,1) = 1

c(2,2) = 45*pi/180

 

the dimensions of (2,2) are because only one term, i.e., the fundamental makes up the vector component and thus only a 2 by 2 matrix is needed. If the vector component were to have more harmonics, the row dimensions would be one greater than the largest harmonic number.

 

The mass variable can be created as in the following:

mass = 100.

 

All that has to be done now is to save variables a, b, c, and mass in a mat file and then load them from within Calcgate fourier series. The same procedures can be performed to initialize the f(t) and f(x) components for the Area program verison of the fourier series program, however, the sum of the f(x) vector components do not have to be equivalent to f(t).

 

The fourier series program can now calculate work, energy, and integral area of a fourier series, for several thousand harmonics in a reasonable amount of time because of the introduction of a new additional mathematical theorem which is equivalent to the transform function, however is much easier to use. Future versions of the fourier series program will be accurate to even more decimal places, for any given defined force or other co-variant f(t) function input, and allow even more harmonics to computed much faster (including the equivalent of more harmonics) by using discrete values for both the force and integral area vector component(s), along with linear and exponential interpolation, with accuracies of 8, 12, and 16 decimal places for any given equivalent harmonic series input. Purchasers of Calcgate will be offered an upgrade at reduced prices when the updated version becomes available.
