How do I save a matrix of integers to a text file in Matlab?

Question

I have a 2D matrix myMatrix of integers which I want to save its content to a text file. I did the following:

save myFile.txt myMatrix -ASCII
         


        

Answer 1

To write myMatrix to myFile.txt:

dlmwrite('myFile.txt', myMatrix);

To read the file into a new matrix:

newMatrix = dlmread('myFile.txt');
