Convert a matrix from Ascii to binary

I have a matrix, dimensions 17272 x 9, and i want to convert it into a binary file. The matrix includes negative elements!! Can anyone help?

What's it look like, how's it stored?

[Walter Roberson]

outputfid = fopen('YourFile.bin', 'w');

fwrite(outputfid, YourArray);

fclose(outputfid);

The above creates a binary file.

Note: a "binary file" is not the same thing as a file in which each byte of the file is used to represent one bit of the data, such as '00010011'

Thank you Walter, it's pretty much it! And what I need is exactly a binary file :)
