Hi. I have symbolic expressions in a script file (that represent calculated partial derivatives. Because I need, at each iteration, that get the numeric value of the symbolic expression depending on the new set values of variables, I created a function, that compute this) Since that symbolic expression is different from case to case, is there a possibility that the expression automatic import in function without manual typing these expressions. I want to define this expression in one place in the script file, and than when you call functions, this expression be automatically loaded in function. Thank you in advance.

Accepted answer

Perhaps you want to use matlabFunction() ?

Thank you dear Walter. The same can be achieved if we take

f = matlabFunction(fs);

If we then use command for automatic save and form function 'state'

g=matlabFunction(f, 'file','state');

fk=state(xk(1,k-1), xk(2,k-1), xk(3,k-1), xk(4,k-1), xk(5,k-1), xk(6,k-1), xk(7,k-1));

Thank you again, you sent me to the right way.
