Hello, I have a 1 x 9 vector which contains all zeroes apart from one element which will take a +ve or -ve number, it's index will change, how do i extract this non zero number in Simulink? Is there a block for it?

A quick search for "simulink nonzeros" returns as its first link this find block. If you set the Show output port for nonzero input values to true, then you'll get the nonzeros values.

This gives the index but not the value I think

nonzeros - EDITED
Use it in a Matlab function block?

No I mean, I want to use it with only simulink library components

If all the other elements are zero, and you don't need the index, then Sum of Elements block would do the trick.
