Hi,
I am having experimental data values i.e (Actual data & modelled data)
I want to match modelled data to my actual data.
Modelled data is function of a variable 'P'
Value of 'P' comes from 2D map. Ultimate goal is to obtain optimized 2D map.
I know to optimize this data in Excel solver where it uses GRG non linear function.
How to carryout this in MATLAB?

This very old question/answer from the Mathworks Support Team indicates that there is no MATLAB function for the generalized reduced gradient method, and suggests fmincon from the Optimization Toolbox as an alternative.

MATLAB's fitnlm() builtin function works for nonlinear regression analysis in your exercise you can use it. See this help documentation how to employ fitnlm(): https://www.mathworks.com/help/stats/nonlinear-regression-1.html
