I'm trying to Export a Matrix to a .txt file with the following Code

with open('outfile.txt','wb') as f:
   for line in M:
        np.savetxt(f, line, fmt='%.4f') 

The Problem is that the file that I obtain, sparates the numbers in different rows, ant it looks something like:

0.0000 0.0000 0.0000 0.
0000 0.0000 0.0000 0.0000 -0.2
998 -0.2966 -0.2945 …

How could I tell python to use each row of the Matrix M as a new complete row oth the .txt file?

Thank you in advance

If this is a 2-D matrix. The easiest thing to do is make sure it is in numpy format and use numpy.savetxt().

How can I save matrix to .txt file? - MATLAB Answers, I have numerical matrix size of 64*60 and I like to save it to .txt file. How can I do it as easy as possible? without repeating %d with fprintf? I have a R object say: mat <- matrix(1:100,nrow=20) I want to send this matrix to .txt file so that the exported .txt file contains 20 rows and 5 columns.

You can use Python's built-in file object like such:

M = np.random.randn(10,10)
f = open("outfile.txt","w")
for row in M:
    for el in row:
        f.write("%.4f" %el + ' ')
    f.write('\n')
f.close()

note that this print a new line everytime a row has been fully printed.

  • it's not recommended to save numpy arrays as txt files. You can use this to save it as .npy binary file
  • Thanks but I need it specifically in .txt format
