Error : Invalid Setting for input port dimensions Demux
How am I suppose to split the elements of a 2D Vector into individual signals. The output vector contains two elements.I tried several methods but am unable to fix the problem.
I don't understand why even after using a Demux for splitting the elements both output elements are routed through a single signal as shown in the Image.

This should support multi-dimensional arrays and, in general, gives you more control than Demux blocks.

Hello,
Please help me in solving this.
I have a column matrix(3*1) which is the output obtained from some matrix operations. I want to use these column matrix elements as seperate inputs(go to blocks) for another one. How to get these matrix elements seperately?
when I tried using demux the output dimensions are (3*1) same as input which I cant use as input for other one. Also I tried using selector block but i didnt understand how this selector block will help me in seperating the column matrix elements.
Also i tried matlab function block next to the column matrix in order to use 'matsplit' command to split the matrix elements. But i am getting error as invalid command. I am using R2017b version for my work.
Please suggest me.
Thankyou in advance:)

Use three output ports on the demux; each one will get one if the input values.
