Hi,

I have:

solveload=[0 0 0 'x' 'y' 'z'];

And need to determine only the position of the x, the y, and the z, when they could be anywhere in the vector, with 0's elsewhere. I'm finding I need a bunch of if-then's. It must be easier?

Thanks in advance :)

Dave

There seem to be missing information.

What characterises ‘x’, ‘y’, and ‘z’?

What makes them so difficult to find? Range? Real/Complex? Something else?

This works:

find(ismember(solveload,'y')==1)

I’m glad you solved it, because I have no idea how to differentiate x, y, and z from your description.
