Can anybody help me by guiding the way to model below piece of code? Its array of structure and I wrote class files for Enum and created Simulink.Bus & Simulink.BusElement to define the structure. Now I'm struck at creating the array of structure in modelling/stateflow. Please suggest.

typedef struct { uint16 str_mem1; int16 str_mem2; Enum_1 str_mem3; Enum_2 str_mem4; } strct_1;

typedef enum { Enum_mem_1 = 0 ,Enum_mem_2 ,Enum_mem_3 } Enum_1;

typedef enum { Enum_mem_4 = 0 ,Enum_mem_5 ,Enum_mem_6 } Enum_2;

static strct_1 Arr[10];

int16 fun_1(Enum_1 str_mem3, int16 abc) { int16 cnt1; int16 val = -1;

for(cnt1 = 0; cnt1 < 10; cnt1++)
{
  if(Enum_mem_4 == Arr[cnt1].str_mem4)
  {
    Arr[cnt1].str_mem1 = 1;
    Arr[cnt1].str_mem2 = 2;
    Arr[cnt1].str_mem3 = 3;
    Arr[cnt1].str_mem4 = Enum_mem_6;
    val = cnt1;
    break;
  }
  else {}
}
return val;
}

It would be of great help if someone can send me a sample model at renish_halo@yahoo.com

I found a way to resolve it. Use class files to define the ENUM Use simulink.bus and Simulink.BusElement to define your STRUCTURE. Then using the mpt.Signal, define your array with DataType as Bus: Name. Now using the Data Store Memory, Selector and Assignment block, you can play around with Array of Structure. This worked with R2013a version of MATLAB. Not sure about previous versions.
