How to select eaach element from a matrix multiplication with bus selector

I have a nxn Jacobian matrix and a nx1 vector that I multiplied and the result is a nx1 vector. I need to select each element there. Does anyone know how to select these with for instance bus selector? Becouse I need to do some operations with each element.

Matlab R2014b

Thanks in advance

Use a Bus Selector or a Demux.

well the bus selector does not work. it does not show the option os signals when trying to implement in the workbench. and I'm not sure about demux either.

If you want us to help, you should explain more than just "does not work" or "not sure".

Kl. The reason a bus selector does not work is that bus selector should have a bus creator before. Otherwise bus selector does not know what signal to choose. The demux works good but I had to double control it by reading lines of outputs. But for now it works good and we can now close this.

Indeed, that's exactly the advantage of using bus over just mux. Nevertheless glad it all worked out.
