Evaluating polynomials in Matlab

  1. Jun 12, 2008 #1
    I defined x as a syms, then work with polynomials involving x. But then I can't find an evaluation command for these polynomials at some x value. Anyone knows how I can get it to work? Thank you in advance.

    There's another system where you can define polynomials just like matrices, e.g. x^2+1 as [1 0 1]. But they only have elementary manipulation, and it becomes really cumbersome doing integral or derivative. (that was why I went the traditional way, which is the one mentioned above).
