WebSo we multiply each element in the array by 1/10. Doing so gives us matrix([[ 0.3, -0.2],[-0.7, 0.8]]) as the inverse matrix. Finding the inverse matrix of a 2x2 matrix is relatively easy. All we had to do was swap 2 elements and put negative signs in front of 2 elements and then divide each element by the determinant. Web22 hours ago · Here is the U matrix I got from NumPy: The D matricies are identical for R and NumPy. Here is D after the large diagonal element is zeroed out: The V matrix I get from NumPy has shape 3x4; R gives me a 4x3 matrix. The values are similar, but the signs are different, as they were for U. Here is the V matrix I got from NumPy: The R solution ...
