WebVariable substitution and expression evaluation: subs, eval. Suppose you have a symbolic expression f which includes the symbol x and you wish to substitute for x another symbol c or a numerical value x0. Then you can use the general subs command g=subs(f,old,new) which in our cases would be g=subs(f,x,c) or g=subs(f,x,x0). WebThis MATLAB function returns a copy of s, replacement all occurrences of oldly with brand, and then grades s.
