how to pass a complex structure to a matlab routine called by C# application?

Can I for example pass into a matlab routine called by C# application, a structure like this:

struct Struct2
{
  int value5;
}

struct Struct1
{
   int value1;
   int value2;
   Struct2 value3;
   Struct2[] value4;  
}

Hi,

yes, you can. You build up the MATLAB structure using the MWStructArray class, something like

String[] val5 = {"value5"};
MWStructArray value3 = new MWStructArray(1, 1, val5);
// fill value3 
MWStructArray value4 = new MWStructArray(1, 5, val5);
// fill value4
String[] s1 = {"value1", "value2", "value3", "value4"};
MWStructArray Struct1 = new MWStructArray(1, 1, s1);
// fill Struct1

Take a look at matlab_root\toolbox\dotnetbuilder\Examples\VS8\NET\PhoneBookExample\PhoneBookCSApp\PhoneBookApp.cs for an example (or the doc at

web([docroot '/toolbox/dotnetbuilder/ug/brl3b0g-1.html'])

Forgot to mention: this is while assuming you are using Builder NE for compiling the MATLAB code...?

I do not know the answer for C# . If it were C, then the theoretical answer would be NO, but the practical answer would be "Yes, as long as you do not want to access the contents of the structure and just want to pass its address".

MATLAB structures are quite different internally than C or C++ or C# structures.

Hi,

there is an interesting blog article which shows recent advances in Builder NE that make this easier then what I wrote above: http://blogs.mathworks.com/loren/?s_cid=global_nav
