Once you've entered the expression, click the &# 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. All Coefficients of Polynomial. Find all coefficients of a polyBecause the symbolic summation is the outermost operation, first app Description. n = norm(v) returns the 2 -norm of symbolic vector v. example. n = norm(v,p) returns the p -norm of symbolic vector v. example. n = norm(A) returns the 2 -norm of symbolic matrix A . Because symbolic variables are assumed to be complex by default, the norm can contain unresolved calls to conj and abs. example.
