Hello everyone, My current code is the following:
chooseEquation = 'poggiolini';
for att_db=0.18/1e3:0.01/1e3:0.20/1e3
dirname =sprintf('C:/Documents and Settings/JAY/My Documents/MATLAB/simplifyCode/data %d',att_db);
mkdir(dirname);
[ResultsPogQPSK1] = MaxReachAnalytical(chooseEquation ,att_db);
fname= sprintf('%s/ result.dat',dirname);
save(fname,'ResultsPogQPSK1');
end
mydata = load(fname);
figure(1);
plot(mydata.ResultsPogQPSK1.reach*1e-3, -8:0.1:3, '-.b', 'LineWidth', 2); hold on; grid on;
I am getting two errors that I do not understand. They are:
??? Error using ==> load
Number of columns on line 1 of ASCII file C:/Documents and
Settings/JAY/My Documents/MATLAB/simplifyCode/data 2.000000e-004/
result.dat
must be the same as previous lines.
Error in ==> PlotAnalysisCurves at 13
mydata = load(fname);
Could someone kindly explain what I am doing wrong? Thank you very much!

You are save()'ing files to .dat filenames but you are not specifying the -ascii option, so MATLAB is saving them as binary MAT files that happen to have funny names. MATLAB does not save() as text unless you use -ascii specifically, but MATLAB does not load() as binary unless the filename ends in .mat or you specify the -mat option specifically when you load()

save with -ascii, or name the files as .mat, or load with -mat

Well I would guess the first line of the ASCII file does not have the same number of columns as the rest of the lines...

Hi Sean, im only working with .mat files and so I am not sure what exactly the ASCII file refers too. Do you know how to fix this error?

It looks like a *.dat file
