I want to get the ones by row. Using above code, I get the number of ones by column.
squeeze( sum( t(1:7, :, :) == 1, 1 ) )
ans
1 1
0 0
0 0

For each row, I want to get the number of ones. In t(:,:,1) , there is ones in row 1 and row 7
.In t(:,:,2) , there is ones in row 7.
The number of ones to becounted is starting from row 7 untill the 1st row for both matrices.
