how to get multiple output in legacy code tool

Hai, Am try to achieve multiple output from LCT. I have written a .c and .h files as bellow

assign.c

#include “assign.h” Int assign(int In_1, int In_2, int In_3) { Int *Out_1, *Out_2, *Out_3; *Out_1 = In_1; *Out_2= In_2; *Out_3= In_3; }

assign.h

#ifdef ASSIGN_H #define ASSIGN_H Int assign(int In_1, int In_2, int In_3); #endif

And my legacy code is look like

def = legacy_code('intialize'); def.SFunctionName = 'sfun_addnum'; def.HeaderFile = { assign.h'}; def.SourceFile = { assign.c'}; def.OutputFcnSpec = ‘assign(int16 u1, int16 u2, int16 u3, int16 y1[1], int16 y2[1], int16 y3[1])’; legacy_code('sfcn_cmex_generater,def'); legacy_code('compile',def); legacy_code('slblock_generate',def);

Out of this codes I can able to generate a SFunction.c and Sfunction block also. But when I try to simulate the matlab get crashed. Please if any one knows the reason please share with me and also if you have an idea about how to get multiple output variables in LCT by using single c function return.

Hi I hope that you get a solution for your problem .

if not yet the solution is :

assign.c

#include “assign.h”

Int assign(int In_1, int In_2, int In_3,Int *Out_1, int *Out_2,int *Out_3)

{

*Out_1 = In_1; *Out_2= In_2; *Out_3= In_3;

}

that's it .

Hope that tis will work for you ;) .
