I've received a script, created a file and put the code in it. While running I receive this error. As it is a script (not a function), there should not be a problem. Does anybody can guide me?

As you mentioned that it is main scripts (Not associated function call). The error clearly stated that "Undefined function or variable"
May be you using the any custom function within the code, which is not defined in the current working directory Or you didnot defined any variable, before it is used. Please check it carefully or share the code, so that we can point the exact error.

Can you show us the full and exact text (including all the text displayed in red) of the error message you received?

Actually I changed the m.file's name and now the error is as follows:
Undefined function 'isfile' for input arguments of type 'char'.
Error in basic (line 44)
if isfile(strcat(inPrefix{z}, '.txt')) % Check if txt file exists, and continue if it does.
