Hello!

I need to call .net method from dll. Method has few "ref" arguments.

C# code:

public static String FillData(ref Struct_Nodes struct_Nodes, ref Struct_Branches struct_Branches)

Matlab code:

a = some.namespace.Struct_Nodes();
b = some.namespace.Struct_Branches();
some.namespace.FillData(a,b);

But "a" and "b" were empty after matlab call.

If I call next C# function with 1 "ref" argument and wthout return value:

public static void FillNodes(ref Struct_Nodes struct_Nodes)

then I can get ref argument by return value:

a = some.namespace.Struct_Nodes();
b = some.namespace.FillData(a);

But "a" was empty, but "b" was filled with correct first argument values.

How can i correctly call .net function with multiple "ref" arguments?

Thank you!
