Attached contour map with a range X-AXIS=[123-131] & Y-AXIS=[33-43] needs to be digitized and interpolation for a 0.1 x 0.1 grid.
I used Webplotdigitizer(<http://arohatgi.info/WebPlotDigitizer/>) to get values at the known points and placed in excel sheet(Attached). Also i have attached the code which can interpolate these values and give me matrix of (100 x 80) [ 43-33/0.1=100 & [ 131-121/0.1=80] I am facing problem in interpolation ,as it give errors.So can anybody please look in code.

This issue might be due to the fact that there were some change in all the 'interp' functions in MATLAB release R2013b. As a workaround, consider the in-built function 'griddedInterpolant' instead of 'interp2' to achieve the same goal.
For more details about 'griddedInterpolant', refer to the following link:
