Hi,
I want to plot 3D contour in MATLAB. I have three dimensions (X, Y,X) and value of each value in specific grid.
Please help.
I have attached sample data set for the same.

To read your data:
[my_data headers] = xlsread('test data.xlsx');
But you present 4D data: 3 coordinate and value. Yo have to choose what to plot against what. For example:
>> x=my_data(:,1);
>> y=my_data(:,2);
>> z=my_data(:,3);
>> tt=my_data(:,4);
>> plot3(x,y,tt)
>> tt2=reshape(tt,51,121);
>> contour(x(1:51),y(1:121),tt2')
