Is there a way where I can calculate the inverse of a mxn non-square matrix using numpy? Since using la.inv(S) seems to give me an error of ValueError: expected square matrix

To calculate the non square matrix mxn, We can use np.linalg.pinv(S), here s is the data you want to pass.

You are watching: Can a non square matrix have an inverse

For square matrix we use np.linalg.inv(S), The inverse of a matrix is such that if it is multiplied by the original matrix, it results in identity matrix.

note: np is numpy

We can also use np.linalg.inv(S) for non square matrix but in order to not get any error you need to slice the data S.
