Converting .mat file with integer values to .dat causing wrong placement of the floating point

Hi,

I am using Matlab R2018b. I have a mat file that looks like the following:

TimeSeries1 = [10 100; 11 101; 12 101; 13 102; etc] but longer and if I open I can see that the values seem correct

Col1 Col2

11 100

12 101

13 101

14 102

....

I tried to convert the .mat file to a .dat file as one of the algorithm I need to use requires a .dat file. So I did the following:

save TimeSeries1.dat TimeSeries1 -ascii

When i double clicked the dat file and opened it, it looks like this:

e00 e1

1.1 1.00

1.2 1.01

1.3 1.01

1.4 1.02

I don't understand why the '.' after the first character even though the data in the .mat file doesn't have that.

Do I do sth wrong?

Thanks for the help.

save writes text files using exponential notation. If you don't want exponential notation, don't use save

In any case, using csvwrite or dlmwrite or writematrix or writetable etc. are preferred for writing text files. Or for full control over the file format, use low-level fprintf.

Thanks for the prompt answer Stephen!

I checked the functions you've suggested and already the dlmwrite function does exactly what I wanted.

I simply typed the command below and problem solved. Cheers.

dlmwrite('TimeSeries1.dat', TimeSeries1);
