this is part of my code inside sfunctions:

#define OUTPUT_MIP(value)        y[6] = (value)
#define OUTPUT_MAS(value)        y[7] = (value)

Output of sfunction block is one wire (vector or array of all outputs)...so i put a demux and seperate them into individual variables...

what i want is to combine the 6th and 7th variable into an array variable, say y[6] and see both of them together in one wire after demux stage at the output of the sfunction block...

hope its clear...pls post ur suggestions...thanks

You should just need to configure your S-function so that the numbers of output signals is 2, instead of 1, and set the output size of port#2 as 2. Then, refer to the second output port to assign values to it. I would recommend looking at some S-function demos to get started on this. Please run "sfundemos" at the MATLAB prompt to see examples of S-functions.
