How to simplify a symbolic matrix - MATLAB Answers - MathWorks

WebUsing Symbolic Math Toolbox™, you can differentiate and integrate symbolic expressions, perform series expansions, find transforms of symbolic expressions, and perform vector calculus operations by using the listed functions. When modeling your problem, use assumptions to return the right results. See Use Assumptions on Symbolic Variables. Web1 Symbolic expressions cannot contain exactly “double precision” numbers, but you can get floating-point numbers: c1 = a + b + vpa (pi)*b or c2 = vpa (a + b + 0.5*b) Some computations, like solve or int, will still switch to exact numbers internally, but your results should always have the floating-point form.
