Hi,
I wrote following code to return multidimensional array from pointer function.Input parameter of this function is one dimensional array, output is pointer that point multidimensional array.
[code]double **function( array< double>^ data,int width,int height )
{int i;
//define returning variable that point multidimensional array
double **R;
// memory allocation for R
R=new double *[height];
for (i=0;i^ >^ input = gcnew array< array< double >^ >(M);
for (j=0;jLength;j++){
input[j]=gcnew array(N);}
// define result1 and result 2 pointers and memory allocate for these variables
double **result1;
result1 = new double *[N];
for(i=0;i<N;i++)
{result1[i]=new double [M];}
double **result2;
result2 = new double *[N];
for(i=0;i<N;i++)
{result2[i]=new double [M];}
//............
// send first row array of multidimensional array to function
result1=function(input[0],M,N)
// send second row array of multidimensional array to function
result2=function(input[1],M,N)
// delete result1 and result2
for (i=0;i<N;i++)
{delete R[k];}
delete R;}
return 0;
}[/code]
I built this program succesfully in Visual Studio 2008.When I debug this code,the program computed [b]result1[/b] but during computing [b]result2[/b] in the function here:
[code]R=new double *[height];
for (i=0;i<height;i++)
{
R[i]=new double [width];
}[/code]
Visual Studio give this error:
[b]An unhandled exception of type 'System.Runtime.InteropServices.SEHException' occurred in stdeneme.exe Additional information: External component has thrown an exception.[/b]
Unfortunately I can't understand this error. How can I overcome of this problem?Could you help me please?
Best Regards..

But I noticed that you have a severe memory leak here:
for (i=0;i<N;i++)
{delete R[k];}
delete R;
This should be
[code]for (i=0; i<N; i++)
{
delete [] R[k];
}
delete [] R;
[/code]
