C++ vector inverse

WebC++ Vector pop_back() It deletes the last element and reduces the size of the vector by one. Syntax. Consider a vector v.Syntax would be: Parameter. It does not contain any parameter. Return value. It does not return any value. The following illustration show how pop_back() function works : WebCompute the (multiplicative) inverse of a matrix. Given a square matrix a, return the matrix ainv satisfying dot (a, ainv) = dot (ainv, a) = eye (a.shape [0]). Parameters: a(…, M, M) array_like Matrix to be inverted. Returns: ainv(…, M, M) ndarray or matrix (Multiplicative) inverse of the matrix a. Raises: LinAlgError
