Hello,

find(NameOfMatrix==ValueThatYouknow)

This will give you the exact position of the value that you want in the matrix that you have! If you want, you can use any condition to know the position of other values!

Hope it helps!

Go for logical indexing:

S = load('soc.mat') ;
t = S.soc.Time ;
y = S.soc.Data ;
idx = abs(y-70)<10^-5 ;
[t(idx) y(idx)]

You're testing only for the one case in which the score is precisely 0.5, for the disp statement not that the score is a multiple of 0.5.

The syntax is wrong for find, the second (optional) argument is the number of elements to find and must be an integer, not the value to match. find evaluates a logical condition so the correct syntax to find the element in the lookup array would be

if find(vec==score)

That is, however, a somewhat wasteful approach, consider what

mod(score*10,5)

returns for various scores and what test would satisfy the condition desired? Then you can simply ensure that the score is also >0 and <= whatever the maximum allowable would be.
