Absolute error between each parameter of the ground truth and estimated planes?

So I have a plane on the xy axis made by meshgrid(x,y). I got estimate parameter by

A = [x, y, ones(size(z))];

parameter_estimate = A\z;

So howdo i find the absolute error, is there a function I can use?

Hi

You can find the absolute error between ground truth and estimated plane by taking the absolute value of their difference using 'abs' function. For example, consider the below command:

absoluteError=abs(parameter_estimate-groundTruth)
