How to save a matrix as text file?
311 views (last 30 days)
I want to save a matrix as text file.
Each column should be separated by tab.
The output file should be read with any text editor
When the output is opened, it should display the numbers
in the same way it looks like in Matlab.
Thank you for your help

One way is to use FPRINTF.
A = round(rand(6,7)*9) % Write this to file.
fid = fopen('Mymatrix.txt','wt');
for ii = 1:size(A,1)
Changed the 'w+' to 'wt' in the FOPEN call.
If you have floating point numbers, you may want to use '%20.18f \t' instead of '%g\t' or similar. See FPRINTF for format specifiers.

You could also consider dlmwrite telling it to use \t as the delimiter.
You could also consider using
save('MyMatrix.txt', 'A', '-double', '-tab')
Where A is the name of the variable
