Question

I am creating a .dat file with headers and data in Matlab, however when I try opening it from the folder where it is saved then I get the error that says 'file in use by another application and cannot be accessed'. This error occurs even when Matlab is closed. I can only open it as a text by right clicking on the file through the Matlab’s current directory window. Why is this happening and how to resolve it?

Answer 1

You could try:

fclose('all')

to close all open files.
