Call a portion of one function from another one

I wrote a relatively large code for analyzing an image, which contains several smaller functions that are called in a big loop. It also includes the uigetfile function at the beginning to select the input image. What I need to do is create another function (new .m file) that calls the above function to analyze a list of images identified in a directory using uigetdir. How can I do that? In short, the new function should only call specific portions of the other code (avoid uigetfile and possibly other smaller parts).

You can only call the (main) function that is the name of the .m file. If you need to call a sub-function from that main function file, you need to create a new .m file for the sub-function or copy-and-paste into the other main function file.

for example, you have this file:

main1.m
function main1
function subfuction1
function subfuction2

You want to call subfunction1 in your main2.m, you can either copy-and-paste the subfunction1 into main2.m or create a subfunction1.m

Thanks Timmy. I was hoping for a way to call an .m file, say from line 15 to line 200! That would be really handy and make coding more concise. I have read that function handles can be useful, but never used them before so I'll just follow your suggestion.
