It looks pretty nasty with all those square root terms, but they actually cancel out quite nicely as we’ll see here in a second.Let’s plug A=QRA=QR into the least squares equation. Doing so yields the following simplified form:

least square fitalgorithmscomputer calculationsA new algorithm for solving a linear least-squares problem with linear constraints is presented. The constraints can be equality constraint equations and nonnegativity constraints on selected variables. This problem,while appearing to be quite special,is the ...
