filename='14 - sampleMap.xlsx';
[num,raw,txt] = xlsread(filename);
txt=cell2mat(txt)
figure,plot(num,'DisplayName','num')

You can use fit() function from Curve Fitting Toolbox. For Gaussian surface fitting use it as
fit([x, y], z, 'a*exp(-( ((x-b)/c)^2 + ((y-d)/e)^2 ) ) + f')
the character array specifies the general Gaussian function in 2D.
