Hi all, For a course in Dynamics of Machines I've ran into an issue with the matlab symbolic toolbox. For a simple system I derive the constraint equations expressed in symbolic coordinates in ...Compute Absolute Value of Complex Numbers. Compute abs(x)^2 and simplify the result. Because symbolic variables are assumed to be complex by default, the result does not simplify to x^2. syms x. simplify(abs(x)^2) ans =. abs(x)^2. Assume x is real, and repeat the calculation. Now, the result is simplified to x^2.
