I am trying to calculate some function with Mathematica and move it to the Matlab, and I would appreciate it if you help me.

1. The Tomatlab.m produces Derivative(1)(sin)(2.*y) from Mathematica to Matlab. However, there is no function like Derivative(1)(sin)(2.*y) in Matlab. So, I was wondering how Derivative(1)(sin)(2.*y) is calculated? Is it cos(2.*y) or 2*cos(2.*y)? in Matlab Code?** The different representation says that Derivative(1)(sin)(2.*y) = sin'[2.*y]., but still not sure sin'[2.*y] = cos[2.*y] or 2cos[2.*y]

2. Even if I use the Tomatlab.m file, I have to modify my code in Matlab to run the code. For example, I have to change (s+(-1).*t) to bsxfun(@minus,t,s'). Since my code is complicated, I have been struggling with the dimension error when I changed these things. Is there any function or file like Tomatlab.m that I can directly use the code output without modification? I saw that there is another function Math link that transfer the code output from Mathematica to Matlab. Any Ideas about this function?

Thank you.
