Hey all

how can i find all rows other than a particular row in a matrix?

    matrix = [1,1,1,0,0;0,1,1,1,0;0,0,1,0,1]
    result = {[2;3];[1;3];[1;2]}

e.g. if we are considering row 1 then all other rows in matrix will be shown in result except row 1

criteria is that if diagonal element e.g. for row1 its (1,1) is 1 then take other rows except from 1. Same will for applied for 2,2 and 3,3.

Cell array is good option but I Can get results in double array as well.

Let's say you have N rows.....and you have selected M'th row, then use Setdiff to get what you want.

N = 12 ;    % 12 rows 
M = 3;      % selected 3rd row
iwant = setdiff(1:N,M)
