3D surface measuring data

Hello guys,

Im using this code to measure a 3D surface from 2D images, but i got an error and i still can't fix it. Can you guys check it, im a newbie in matlab.

We don't have the input to run your code and we don't know what is your error to help you. What you expect?

This is the error i get,

>> im_analyze5_2

Index exceeds the number of array elements (9).

Error in im_analyze5_2 (line 51)

im(i).image = imread(strcat(im_dir , files(im_list(i)+2).name));

and here i attach the images, and i expect 3D surface wit x,y,z value in mm instead like this picture

im_list(i)+2

why +2 ???

I get this code from paper that I read, I want to do the same thing like the paper but with my file images. I don't know what changes must I do to make it works. I've tried so many time, but I attach the original code so you can see where I begin,
