Question on error obtained

I am getting the following error...

Error: File: sub_map_ar_3.m Line: 2 Column: 37
Function with duplicate name "sub_map_ar_3" cannot be defined.

Error in HazKTM_3atn_final (line 185)

Just rename the function name so that you don’t get the error again.

which sub_map_ar_3 -all % will show you the existing files with the name

Your sub_map_ar_3.m contains an executable line in the first line, followed by a function definition for sub_map_ar_3 on the second line. The executable line makes it into a script file instead of a function file. When you have a script file that contains a function (which is permitted from R2016b onwards) then the function defined inside the file cannot have the same name as the script file.

You should check the first line of your sub_map_ar_3.m to see whether you accidentally inserted some text. If you put something like "clear all" in at the top of the file, that should definitely be removed.
