So why doesn't this work?

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?

[KL]

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?

[Wouter Stg]

What i want in Z is

out of y for the rownumber the number in x (x1)and for

the columnnumber the collumn of y (y(:,3)???

and than a sequence of it from in the exaple 1-4)

I want in Z the sequence in y from collumn 3 in z) so

[1; 7; 88; 19;] is what i want in Z

z=y(X(1):X(4),3)
