Hello! I am trying to export some code done in Matlab to a C# project via the matlab Coder and compiling it into a .dll file. It works nicely for handling arrays of a set size but when I choose the input argument in my Entry-Point Files to be an array of variable size "Up to 4 (:4)" something goes wrong.
I have previously tested returning a set sized array "Exactly 4 (4)" which works fine.
Here is the Matlab code, quite simple:
function [ out ] = divideArray( in )
out = in / 2;
end
Here is the extern function that is generated in the divideArray.h file:
extern void divideArray(const real_T in_data[4], const int32_T in_size[2], real_T out_data[4], int32_T out_size[2]);
Here is the C# code, first the DLL import declaration:
private static extern void divideArray( [In] double[] arrIn,
[In] int[] inSize,
[Out] double[] arrOut,
[Out] int[] outSize);
And then the C# main funtion:
static void Main(string[] args)
{
double[] foo = new double[4] { 1, 4, 9, 43 };
double[] bar = new double[4];
int[] inSize = new int[2] { 1, 4 };
int[] outSize = new int[2];
divideArray(foo, inSize, bar, outSize);
Console.WriteLine("\ninSize:");
Console.WriteLine("Length: " + inSize.Length);
Console.WriteLine("[0]: " + inSize.GetValue(0));
Console.WriteLine("[1]: " + inSize.GetValue(1));
Console.WriteLine("\noutSize:");
Console.WriteLine("Length: " + outSize.Length);
Console.WriteLine("\nbar values:");
for (int i = 0; i < 4; i++)
{
Console.Write(foo.GetValue(i) + " ");
}
Console.WriteLine("\n\nDone.");
Console.ReadKey();
}
Here is the console output I get:
inSize:
Length: 2
[0]: 0
[1]: 1071644672
outSize:
Length: 0
bar values:
0 0 0 0
Done.
So not quite sure what happens, it works perfectly fine when the input array size is set to a constant but when it is variable the input size is changed and no output is made. I have tested a lot of different inSize values in case the array indexing was Matlab or C but no difference. And again, it works with no problems when the array size is set to a constant :)
Thanks in advance, Viktor
