Calculate the generalized inverse of a matrix using its singular-value decomposition SVD and including all large singular values. It is not possible to divide matrices in Numpy but you can multiply by inversed matrix. Matrix is a rectangular arrangement of data or number or in other words we can say that it is a rectangular array of data the horizontal entries in the matrix are called rows and the vertical entries are called columns.
