WebReturn the least-squares solution to a linear matrix equation. Computes the vector x that approximately solves the equation a @ x = b. The equation may be under-, well-, or over-determined (i.e., the number of linearly independent rows of a can be less than, equal to, or greater than its number of linearly independent columns). Web2. Least squares fitting has the desirable property that if you have two different output values for the same input value, and you replace them with two copies of their mean, the least squares fit is unaffected. For example, the best fit line is the same for the following two sets of data: 0 1 0 5 1 5 2 6. and. cloud screenshot cloud screen share

"Websolution: the least squares solution. It has shape (*, n, k). residuals: the squared residuals of the solutions, that is, ∥ A X − B ∥ F 2 \ AX - B\ _F^2 ∥ A X − B ∥ F 2 . It has shape equal to the batch dimensions of A. It is computed when m > n and every matrix in A is full-rank, otherwise, it is an empty tensor. " - Gedmatch least squares method
