Maybe one of the last two of these four loops was what you wanted:
-->bool2s(y>a)
ans =
0. 0. 0. 0. 1.
-->for k=bool2s(y>a), if k, disp(b), else, disp(y), end, end
- 11. - 6. - 1. 4. 9.
- 11. - 6. - 1. 4. 9.
- 11. - 6. - 1. 4. 9.
- 11. - 6. - 1. 4. 9.
100.
-->for k=y, if k>a, disp(b), else, disp(y), end, end
- 11. - 6. - 1. 4. 9.
- 11. - 6. - 1. 4. 9.
- 11. - 6. - 1. 4. 9.
- 11. - 6. - 1. 4. 9.
100.
Here, k takes the value of each element in y:
-->for k=y, if k>a, disp(b), else, disp(k), end, end
- 11.
- 6.
- 1.
4.
100.
Or maybe this is easier to follow:
-->for k=1:length(y), if y(k)>a, disp(b), else, disp(y(k)), end, end
- 11.
- 6.
- 1.
4.
100.
