%say I have this matrix:
C=[4,10;5,20;6,30;7,40]
%and I want to develop a txt file such that it contains
4, 10
5, 20
6, 30
7, 40
%the dlmwrite function doesn't let me keep the matrix as it exactly looked but rather ask me to decide on the same # of sig figs for all columns such as:
dlmwrite('mytext.txt', C, 'precision', '%.2f','newline', 'pc');
4.00, 10,00
5.00, 20.00
6.00, 30.00
7.00, 40.00
anyone can help how I can make the txt file look like the following and not how dlmwrite does it:
4, 10
5, 20
6, 30
7, 40

type doc sprintf to see all other format, such as %g, %G. You should be able to find what you want.

%g is probably the way to go.
