Reshape a matrix to the target dimensions given by n_rows and n_cols.

np.reshape(mat, n_rows, n_cols)

Returns the dot product of two matrices.

Dot product is also known as matrix multiplication., mat_2) # vector

Returns the cross product of two matrices.

np.cross(mat_1, mat_2) # This is what we multiply 2 matrix like (m x n) (n x m)

Computes the inverse of a matrix.
