This operation takes a real of complex value and produces its inverse. The inverse is one divided by the input value. Note that the calculator produces an infinite result error if zero is inverted.

This operation can calculate the inverse of a matrix. The input must be a square matrix which means it has the same number of rows as columns. The operation will fail if the input is a vector or non-square matrix. The result is the inverse matrix of the input matrix. If the matrix is not invertible, then the calculator produces an infinite result error.
