What norm StepTolerance uses for multivariable?
I want to define a StepTolerance for the lsqnonlin with ‘trust-region-reflective’algorithm to solve a system of 4 variables, so X has dimension 4×1.
The documention Tolerance Details says that this algorithm uses a Absolute Step Tolerance.
In Tolerances and Stopping Criteria I found this:
"StepTolerance is a lower bound on the size of a step, meaning the norm of (xi – xi+1). If the solver attempts to take a step that is smaller than StepTolerance, the iterations end."
Is this norm the same of function norm, the Euclidean norm?I want to define a StepTolerance for the lsqnonlin with ‘trust-region-reflective’algorithm to solve a system of 4 variables, so X has dimension 4×1.
