If you want to open a MAT-file, use this one:
A = open('filename.mat');
Or, A = open('fullpath\filename.mat');
fullpath: is MAT-file's path.

Did you use "clear" at the first line of your code?
Or, another probability is: You added a folder into MATLAB path,that you have another function with the same name in that.

This is not an m-file. It appears to be a .mat file. Kelil, please answer my questions below, and dpb's questions above so we can quit wasting time.

If your function is called snafu.m, then do this on the command line:
>> which -all snafu
And you may have left over variables from a prior run still hanging around in memory that may be affecting your values on subsequent runs. So you might want to call clearvars before each run to clear those out.
And please answer dpb's question since I have no idea what you're asking either. And attach your script and any data files it needs to run.

Use
save('result.mat', 'comm_r');
to save the results as a .mat format file, not a text format m-file.
Then to recall the variable from the .mat file, do this
s = load('result.mat');
comm_r = s.comm_r;

The error seen could easily happen if you accidentally did a save giving the name of the .m file -- for example if you had done
save result.m -mat
If you had just done
save result
then MATLAB would know to use result.mat
Perhaps you used one of the figure menu items to save a figure and did not notice that you had accidentally selected the .m file as the output name.
If you did accidentally save a workspace over top of result.m then the result.m you had is gone, and you would need to recover it from backup (if you have one.) If you are fortunate you might have an autosaved version; see https://www.mathworks.com/company/newsletters/articles/automatically-save-backup-m-files-with-the-matlab-editor.html
