Hello everyone ,
works: 1 2 3 4 5 6
A1 3 1 2 2 3 1
A2 2 3 3 1 2 3
Can I find the value 2 in each row in the matrix given above and print the job number in another matrix?
Example: I found 2 values in row A1 in the given matrix. These are the 3rd and 4th jobs. I need to print these jobs in a matrix like below.
Works: 2

% given matrix with three rows:
M = [ ...
1 2 3 4 5 6; ...
3 1 2 2 3 1; ...
2 3 3 1 2 3];
% value to look for in the second row of M:
val = 2;
% find the indices where val is in the second row of M:
idx = find(M(2,:) == val);
% output is val followed by those indices, all together in a column vector:
output = [val; idx(:)]
