Nettet7. jun. 2014 · 1. Call W1 and W2 the two vectors. For this to work, they must be column vectors. Transpose them if they are rows instead of columns. Then if we wish to find the value of k such that W1 = k*W2, just use backslash. k = W2\W1; Backslash here gives you a linear regression (least squares) estimator, as requested.

If A is not of full rank, A' * A is not invertible. Instead, one can use the pseudoinverse of A. x = pinv (A) * b. or Matlab's left-division operator. x = A \ b. Both give the same solution, but the left division is more computationally efficient.
