WebIf the columns of a matrix A are linearly independent, so AT· A is invertible and we obtain with the following formula the pseudo inverse: A+ = (AT · A)-1 · AT Here A+ is a left inverse of A , what means: A+· A = E . However, if the rows of the matrix are linearly independent, we obtain the pseudo inverse with the formula: A+ = AT· (A · A T) -1
