I am trying to use find command to locate row number of the first elements which meets the condition.
All I am able to do right now is to find elements themselves which meet the condition I gave.
How can find the row number (in matrix A) which meets the condition first. I wanted to use this row number further find relevant element value from another array.
for example:
A=[450;470;490;510;530;550;570];
B=[10;20;30;40;50;60;70];
so if I use condition A>500 , answer would be 40.
I tried using following command
C=A(A>500)
but it is giving me all the values of element and not row number, which further will be used to find element from B array having same row number.
