why fread showing too many output arguments?

I have a function which reads a binary file and extracts the data. I already have entire code. I am trying to run it, but it shows error at

[nmass, nr, np, nk, nm] = fread(id, 5, 'int');
Error using fread
Too many output arguments.

I have a 5D binary data file and trying to extract the data from that file.

Any suggestions, why it is stuck at this point?

Thank you in advance.

"Any suggestions, why it is stuck at this point?"

As the FREAD documentation explains, FREAD returns all of the data in its first output:

The second output (the number of characters read) is not commonly used. In any case, it certainly does not support five output arguments as you show.

Aha! I did that trial an error before.

I get 5-values when I run:

[nmass] = fread(id, 5, 'int');

So, does that mean 5-values represents 5-different parameters?

Yes, if that is what your file contains and the FREAD command is correctly specified for importing that file data.

I moved the comments so the answer can be excepted.
