basename = 'cuboid';

name = strcat(basename,ending);
fileID = fopen(name,'w');

I am trying to write data from a matrix to a text file called cuboid_# where pound is a number given by a for loop index, as I am trying to write many. It works for the first few hundred, but around a = 470, the script fails with the following error:
"Error using fclose Invalid file identifier. Use fopen to generate a valid file identifier.
Error in cuboid_timescan (line 56) fclose(fileID); "
The file ID is consistently positive, so I am not sure what the issue is, especially since it works for files of a lower index.
Does anyone know what the issue here is?
