How to output an array as the output of an sfunction?

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.

thanks.. its like u keep on outputting y[1]=... y[2]=... y[3]=... ........
depending on number of output ports and and size of each port, u either see it as a vector or a single value..

Shyam: Yes, but you also need to tell Simulink exactly how many ports the S-function has and the size of each signal.
