How do I initialize my MWStructArray with two fields and 5 elements.

Hi,

#include "mclcppclass.h"

const char* fields[] = {"a", "b"};

mwArray my_struct(1, 5, 2, fields);

See doc for more:

Thnx. I am calling matlab function from my C# code. Matlab function always accepts MWArray type. I want to send MWStructArray to the method. How do I do that?

Is this about MATLAB Builder NE? Or do you call ML as COM Server from C#? If its Builder NE than: MWARRAY is an abstract class, so creating an MWSTRUCTARRAY and passing it to the ML function will work fine:

MWArray[] result= null;

MWStructArray my_struct= null;

MWStructArray ret_struct= null;

String[] myFieldNames= { "a", "b" };

my_struct= new MWStructArray(1, 5, myFieldNames);

my_struct["a", 1]= new MWCharArray("some text here");

my_struct["b", 1]= 1337

result = your_builder_class_call.function(1,my_struct)

//when you know you get an struct array back do:

ret_struct = (MWStructArray)result[0];

Maybe look at the phonebook example provided in the doc:

Thanx Friedrich.. I was unable to do as I was using MathWorks.MATLAB.NET.NAtive.Arrays. Now i m using MathWorks.MATLAB.NET.Arrays so its working fine.
