As the title says, I am receiving an error saying I have too many open files. I did look into it (via MatlabCentral) and attempted to fix it by adding ‘fclose’ after each ‘fopen.’ I am adding my for loop below. I included the first line of my code (readmatrix), but did not include the lines defining the variables because there are too many. What am I doing wrong here?

Thanks.
