WebWhen you assign a value to a symbolic variable, expressions containing the variable are not automatically evaluated. Instead, evaluate expressions by using subs. Define the expression y = x^2. syms x y = x^2; Assign 2 to x. The value of y is still x^2 instead of 4. x = 2; y. y = x^2. If you change the value of x again, the value of y stays x^2.
