How to delete or exclude an entire matrix if it contains all zeros

3 views (last 30 days)
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.
whos % show variables in the workspace
Name Size Bytes Class Attributes X 10x10 800 double cmdout 1x33 66 char
You can delete variable X with
clear X
Name Size Bytes Class Attributes cmdout 1x33 66 char
The output from whos shows that X is gone now.
