def MatInv(arr,file):
f = open('file.txt','w')
f.write(arr)
f.close()
So I'm trying to write a module that will take a matrix (arr) and write it
to a text file.
The above module is called MatrixIO.py
#first I import it
import MatrixIO
#Then i call the function MatInv with matrix(a) and file name (doc) as the
arguments
MatInv(a,doc)
It creates a file called txt and it shows only boxes. What am I doing wrong?
