How can i save a matrix in a txt file and also in .png format?

I have a 12 by 3 matrix 'A'. I want to write this matrix in a txt file with a Title as well as separate names for each column and row.

For example for 12 rows i want to name them "M1,M2,M3,M4,M5,.......M12" For 3 columns i want them like "37.txt,38.txt,39.txt".

And is it possible to save this in 'png' format?
