Question

suppose this the output c=[0 0 0 0; 0 0 0 0; 1 1 1 1] now how could i delete the other zeros for a looop and only print the last row??

Answer 1

To remove 0, you can simply do: c(~c) = []; you don't need a loop! Beauty of matlab :)

~c is essentially looking for empty values in c. In Matlab, 0 means empty value and you can simply remove it by replacing it with []

>> c=[0 0 0 0; 0 0 0 0; 1 1 1 1]

c =

     0     0     0     0
     0     0     0     0
     1     1     1     1

>> c(~c) = []

c =

     1     1     1     1
