MuPAD generate::MATLAB to include element by element (dot) vector operations

Hello,

I am trying to compute a complicated analytical expression in MuPAD and generate code to implement in a MATLAB function, however I can't get the generated code to support the dot-syntax MATLAB requires for element by element vector operations. Here is a simplified example of what I am trying to do.

In MuPAD>>

f:=(c*z^3)/(a*x^2+b*y^2): print(Unquoted,generate::MATLAB(generate::optimize(f)))

Returns>>

t18 = z^2;

t17 = (c*t18*z)/(a*x^2+b*y^2); (c*z^3)/(a*x^2 + b*y^2)

My ideal output would be:

t18 = z.^2;

t17 = (c.*t18.*z)./(a.*x.^2+b.*y.^2);

There doesn't seem to be an option to select this in MuPAD's generate() help.

Anyone have experience with this?

Thanks,

Kiron

The output is a text string. You can run MATLAB's vectorize() on the string lines.

Thanks for the quick reply!

I did not know about the vectorize() function, that will be useful at some point.

The extra function generate::optimize() can create something like 50 lines of code, but greatly simplifies and speeds up code. Wouldn't I have to run vectorize() on each line of code for that to work?

Right now, I simply find and replaced every '*', '/', and '^' to '.*', './' and '.^'. Crude, but effective.
