Hi all

I have a matrix having some values equal to one. I want to transform this matrix to an array without the one values.

how can I do this? for example a=[13 1 4; 45 23 1; 1 56 78] changed to b=[13 45 23 56 4 78]

cheers,

   a=[13 1 4; 45 23 1; 1 56 78];
   indices = find(a==1);
   a(indices) = [];

Even quicker and cleaner:

a(a==1) = [];
