Hi all,

I want to loop through tables which contains X,Y and Z coordinates of a surface under different conditions. So I want to select first three columns and plot the surface using surf plot. Later, I want to plot the surfaces for different conditions. my table looks like below. So, for example, in remove_sealant_condition, there will be X_disp,Y_disp and Z_disp.

can someone help me with this?

Thanks

Hi @Abdul Rasyid Haron,

To use data from a spreadsheet, the 'readtable' and 'readmatrix' functions can be used to extract the data in the form of MATLAB tables/matrix instead of iterating through the columns. Here's some documentation of these functions:
