Calculating values from string and displaying?

I'm trying to perform a calculation on two values that basically takes the second x, y value in the array "EasyPracNumbers" and multiplies it by 1 to output 2 but instead it outputs:

1
2
3

This is the code:

EasyPracNumbers = [1 1; 2 2; 3 3];
CalcOutput = EasyPracNumbers(:,2)*1;
disp(CalcOutput);

What am i doing wrong, I need to use the function "hypot" on particular numbers in an array and output them to screen also, how would I do this?

>> EasyPracNumbers = [1 1; 2 2; 3 3]
EasyPracNumbers =

     1     1
     2     2
     3     3

and then you do :

CalcOutput = EasyPracNumbers(:,2)*1

it means that you multiply the second column of EasyPracNumbers by one, so yes, it will display [1 2 3]'

Answer 1

[KL]

when you write

 EasyPracNumbers(:,2)

you are accessing the second column. and that's why you get 3 elements. Perhaps you mean

 EasyPracNumbers(2,:) %here 2 is the row number, change it to 1 or 3 as 
                      %you wish

but still i'm not getting what you're trying to do. As far as hypotenuse goes, you might want

 hypot(EasyPracNumbers(1,1),EasyPracNumbers(1,2))

Thanks for that!
