Accepted Answer. MATLAB assumes that symbols might have complex values unless you tell it they are not complex. For complex values, sqrt (x^2) is not the same as x. For that matter, sqrt (x^2) is not the same as x even just for negative real values. If you know for sure that your values are nonnegative, then add an assumption about that, such as.The Symbolic Math Toolbox™ currently does not support composite symbolic functions, or symbolic functions that are functions of another symbolic functions. Create a symbolic function f with variables x and y by using syms. Creating f automatically creates x and y. syms f(x,y) Assign a mathematical expression to f. f(x,y) = x^2*y.Perform algebraic manipulations on symbolic expressions.
