A simplified question for what im doing,

I've got variables

X :[1;2;3;4;5;6;7;8;9;10]
Y: magic(10)and i want to create Z,

Z= (number of x),Yvalue: (number of x),Y value) I tried this

y(x(1),3) which is the correct number i want.

y(x(4),3) which is also the correct number i want.

Now when i try Z= y(x(1),3): y(x(4),3)

I get

Columns 1 through 13
     1     2     3     4     5     6     7     8     9    10    11    12    13
Columns 14 through 19
    14    15    16    17    18    19

What am i doing wrong?

y(x(1),3) is 1 and y(x(4),3) is 19. So by Z= y(x(1),3): y(x(4),3) you mean Z = 1:19. I don't find anything surprising here. Can you explain what do you expect in Z?
