Looking at the matrix structure given above, I want to print jobs with the value 3 in row A1 in another matrix. how can I do it?

Example for A1 ;

new matrix: 8

15

What is a "matrix structure"? Is this a struct containing the vectors 'Works', 'A1' and 'A2'? Please post some code, which creates the array.

What are "jobs"?

I am not certain what the original matrix structure is, so I am taking some liberties with it.

Works =  [5   8  9  15   7  12];
A1 =     [1   3   2   3   1   2];
A2 =     [3   2   1   1   2   3];

new_matrix = Works(A1 == 3)

new_matrix = 1×2

8 15

Maybe your data are:

X = [5   8  9  15   7  12; ...
     1   3   2   3   1   2; ...
     3   2   1   1   2   3];

If so, than:

match  = X(2, :) == 3;
Result = X(1, match).'

Result = 2×1

8 15
