Given a square matrix a, return the matrix ainv satisfying dot (a, ainv) = dot (ainv, a) = eye (a.shape [0]). Matrix to be inverted. (Multiplicative) inverse of the matrix a. If a is not square or inversion fails. WebFind the determinant of f using det. The result is a symbolic matrix function of type symfunmatrix that accepts scalars, vectors, and matrices as its input arguments. fInv = det (f) fInv (a0, A) = det a 0 I 2 + A. Convert the result from the symfunmatrix data type to the symfun data type using symfunmatrix2symfun.
