I have created a 3-Dimensional matrix (remove_bad_data) of size

11*600*14 (rows*coloumns*sheets)

I wish to remove certain rows on each sheet. Eg.

remove_bad_data(10,:,2)=[];
remove_bad_data(3,:,3)=[];

But I get the following error:

A null assignment can have only one non-colon index.

How do I fix this issue?

You can't set them to empty, that'd mess up the dimensions of your array.

Since it is impossible setting them to empty without actually changing your array, you could use NaN instead.

data(10,:,2) = NaN;

For example. Or actually use 0 like the header of your question suggests instead of trying to set them to empty.
