I have total 947(Nspec) files. The file name is 'spec1.dat' up to 'spec947.dat'. Each file consists of two colums with floating numbers. I am running this code in MacOs Catalina and having this error. But the same code runs fine in windows!! I am new to mac and the matlab version i am using is R2019b (both Windows and Mac).

Hey Arup,
"Index in position 2 exceeds array bounds" indicates that there's a mismatch in array dimensions, you are probably trying to access a data point or memory that doesn't exist. You are probably trying to index into an array, but are using indices that exceed the size of the array.
Refer to the Documentation link on Debugging Tools in MATLAB, it may be of help to you.
Hope this helps!

You are using fscanf() on a file you opened for writing ('w') When you opened the file for writing, the entire content of the file would have been deleted, so there is nothing left in it to read.

I have changed it to 'r' but still the same. The problem is the code run just fine in windows but gives this error in MacOS.

It is difficult for us to debug without a copy of the code (not just an image of code) and enough data files to be able to run to the problem.
