Find function - index by rows?
Mostrar comentarios más antiguos
For the find function, I noticed that it indexes downward column by column. Is there a way to make it so that it indexes left to right row by row?

Nope. Transpose your data and start thinking in terms of columns, not rows.

Apply find function to the transpose of your matrix
find(A'==2) % for example

You are not changing your Matrix, your are just operating on another Matrix which is A'

Example:
A = rand(15) > .4; % your array
[i0,j0] = find(A);
c = num2cell(sortrows([i0,j0],1),1);
[i_out,j_out] = c{:};
or jast (as by Azzi)
[j_out,i_out] = find(A.');
