I'm reading a large data set where sometimes there is a matrix of all zeros in all rows and columns. How do I either delete the entire matrix of zeros after it has been read, or exclude MATLAB from saving it in the first place?

@Caitlin, you'll have to be more specific about how you are reading in the data in order to get a useful answer.
X=zeros(10,10);
whos % show variables in the workspace
You can delete variable X with
clear X
whos
The output from whos shows that X is gone now.
