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

You have to convert your matrix to double before using save.

>> myMatrix2 = double(myMatrix);
>> save myFile.txt myMatrix2 -ASCII

Answer 2

Building on snakile's earlier answer: to write myMatrix to myFile.txt, using CR/LF as line terminator ('pc'), otherwise, you should use LF ('unix'):

dlmwrite('myFile.txt', myMatrix,'newline','pc');

To read the file into a new matrix:

newMatrix = dlmread('myFile.txt');

Answer 3

To write myMatrix to myFile.txt:

dlmwrite('myFile.txt', myMatrix);

To read the file into a new matrix:

newMatrix = dlmread('myFile.txt');
