I have mutltiple text files with x, y, and z data attached. This files are named in matrix form according to their location.
I would like to create one surf plot that combine the surf plot of the individual text files. The x, and y data can be continuous row and column numbering but the z data remain the same.
Will appreciate a help. Pls let me know if you need more info.
Thanks in advance.

load() each file. Extract column 3. reshape it as 614 x 588 and then transpose it to 588 x 614. Store in a cell array according to the information from the file name.
When they are all loaded, cell2mat to get the overall Z matrix.

The black lines are the places the subsection was padded on the right or bottom.
