Is the best way to go from research paper from quant trading algo to C via Matlab and MuPAD ?

This appears to be an interesting research development. I was playing with the following functions as displayed:

I just played with this in the Matlab command console:

>> syms x y t
>> z = (x^3 – tan(y))/(x^3 + tan(y));
w = z/(1 + t^2);
F = [w, (1 + t^2)*x/y; (1 + t^2)*x/y,3*z – 1];
>> matlabFunction(F,’file’,’testMatrix.m’,’vars’,[x y t])

ans =

@testMatrix

>> ccode(F)

ans =

F[0][0] = -(tan(y)-x*x*x)/((tan(y)+x*x*x)*(t*t+1.0));
F[0][1] = (x*(t*t+1.0))/y;
F[1][0] = (x*(t*t+1.0))/y;
F[1][1] = (tan(y)*-3.0+(x*x*x)*3.0)/(tan(y)+x*x*x)-1.0;

>> latex(F)

ans =

\left(\begin{array}{cc} -\frac{\tan\!\left(y\right) – x^3}{\left(x^3 + \tan\!\left(y\right)\right)\, \left(t^2 + 1\right)} & \frac{x\, \left(t^2 + 1\right)}{y}\\ \frac{x\, \left(t^2 + 1\right)}{y} & – \frac{3\, \left(\tan\!\left(y\right) – x^3\right)}{x^3 + \tan\!\left(y\right)} – 1 \end{array}\right)
