Hi everyone,

I have A = [1 2 3 4 5; 1 0 0 0 0; 1 2 3 4 5; 1 2 3 4 5; 1 0 0 0 0; 1 0 0 0 0 ]

I want to delete the rows that contain 0 in the bottom. Then I can’t use

condition=A == 0; 
A(condition,:)=[];

as it will delete row 2 as well. I just want to remove the rows in the bottom until the rows start to contain numbers. The number of rows in the bottom can change.

Any ideas? Thanks!!

The description is not clear. Does they mean, that you want to delete the last two rows only? All rows contain numbers, because 0 is a number also. And no row contains zeros only. Please edit the question and improve the description.
