I was playing with the polyfit() function in the surface fitting toolbox to fit a surface to my data, which states that its solves the linear equations using QR decomposition(using Matlab backslash(\) operator).
Is there any mathematical formulation of how these equations are solved using this technique on paper? I am curious to know "top to bottom" theoretical formulation of this method. I just want to understand the maths behind this approach.
Thanks!!
