Is this function write correct: -((exp(-x)*cos(y)+2*x)/(exp(-x)*sin(y))) function is: -(e^(-x)*cos(y)+2x)/(e(-x)*sin(y))). Thanks

I'm guessing are you asking if the function on the left hand side is the MATLAB version of the function on the right hand side? If so, it appears to be correct - although the function on the right has one extra bracket.

It is, but it’s always best to vectorise it:
f = @(x,y) -((exp(-x).*cos(y)+2*x)./(exp(-x).*sin(y)));
Also, see the documentation for meshgrid (and ndgrid) as well), if you want to evaluate it most efficiently for a range of values for ‘x’ and ‘y’.
