Hi,

I have created a symbolic equation on a previous script and saved it as a .mat file

I hvae then opened it in a new script and wish asign variables to gain a numerical value

can anyone help me with this?

solv = open('solvx.mat')
x=solv.solx;
cx = 10;
cy = 10;
r = 2;
b = 30;

Take a look at matlabFunction, it should be the function to use to convert a symbolic expression to a numerical functin.
