Hi,

I am pretty new to MATLAB, so this might be a stupid question. However, I am encountering a problem when i try to convert a matrix of 1x1 symbols into a matrix with doubles, where the symbols are converted to doubles each. Each element in the matrix is a function of a lot of symbols, which I need somehow to convert into numbers. I have something like this:

syms x y; f = function of x and y x = 2; y = 3; f.

However, doing this gives me f as a function of the syms x and y, and not the numbers 2 and 3... Hope you can somehow help me, as Im kinda stuck in my coding.

Regards, Christian

Use

suyms x f=cos(x); x=10; eval(f)
