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
