			==Saving Data to a File==

			If you have variables in your workspace that are processor-intensive to calculate, and that you want to be able to load many times in the future, you can save your workspace rather than re-calculating the variables every time.

			The <code>save()</code> command will save workspace variables to a file.

			===Ascii vs. Mat format===

			The ASCII format will take up a lot more space, because it's saving everything out in human-readable ASCII format. This is useful if, say, you want other programs to read Matlab's saved workspace variables.

			To save a variable 'really_big_variable' to an ASCII file,

			<source lang="matlab">
			save('really_big_variable.txt', 'really_big_variable', '-ASCII');
			</source>

			On the other hand, the MAT format is a binary format, meaning it is more compressed, but not as straightforward for other programs to read.

			To save a variable in MAT format:

			<source lang="matlab">
			save('really_big_variable.mat', 'really_big_variable', '-MAT');
			</source>
