Find function and storing in cell

Hi

I'm trying to write a program that stores the values 0 < X < 1

I have an array X wich are 15000x14 and I want to store the row numbers in a cell every time the values are between 0 and 1

in some cases there are multiple values that 0 < X < 1

How should I write this?

[x,y] =find(0 < X < 1);

when I do this it still gives me numbers that are negative

Thanks Morten

[x,y] =find(X>0 & X<1);

In MATLAB, except for some symbolic contexts, the expression 0 < X < 1 is parsed as ((0 < X) < 1) . The 0 < X part is done first and gives a result that is either 0 (false) or 1 (true). Then that 0 or 1 is compared < 1 and that is going to give 0 where the result of the first comparison was true (because 1 < 1 is false) and 1 where the result of the first comparison was true (because 0 < 1 is true.)

You need to use 0 < X & X < 1

Thanks.

And how can I index the row numbers in a cell?

mask = any(0 < X & X < 1, 2);
rows_with_match = find(mask);
