I am new to .NET programming.....I am trying to write a program that copies a large matrix into a certain format called HDF5 format. The program just has to do this. There are a large number of text files (140). The program just reads the files and converts the text data into integers and stores these in a matrix. So the matrix has 140*1091 rows as each file has 1091 integers. But in the beginning when I give the memory allocation as "const int FSPACE_DIM1 = 1091*100;" the program stops here itself and gives the error:
"An unhandled exception of type 'System.StackOverflowException' occurred in copytohdf5.exe".
I saw the earlier discussion where daniel had the same problem. Swandog46 had given a reply asking him to rewrite the program iteratively so that he could allocate his own memory. I am not able to figure out how to do this. This is my code (It builds and compiles):
// This is the main project file for VC++ application project
// generated using an Application Wizard.

const int FSPACE_RANK = 2; // Dataset rank as it is stored in the file
const int FSPACE_DIM1 = 1091*100; // Dimension sizes of the dataset as it is...

}
}
for(int i=0;i<j*1091;i++)

else
e = (i+1)/1091 + 1;
if(e%20==0)

else

if(e%20==0)
matrix[i][3]=e/20;
else
matrix[i][3]=(e)/20+1;
}
for(int i=0;i<j*1091;i++)
{
cout<<matrix[i][0]<<"\t"<<matrix[i][1]<<endl;
}
inFile.close();
}
//This part is only after reading the file data into the matrix and must work fine once the matrix size problem is cleared..
H5File* file = new H5File( FILE_NAME, H5F_ACC_TRUNC );
hsize_t fdim[] = {FSPACE_DIM1, FSPACE_DIM2}; // dim sizes of ds (on disk)
DataSpace fspace( FSPACE_RANK, fdim );
DataSet* dataset = new DataSet( file->createDataSet( DATASET_NAME, PredType::NATIVE_FLOAT , fspace ));
dataset->write( matrix, PredType::NATIVE_FLOAT );
delete dataset;
delete file;
file = new H5File( FILE_NAME, H5F_ACC_RDONLY );
dataset = new DataSet( file->openDataSet( DATASET_NAME ));
dataset->read( matrix, PredType::NATIVE_FLOAT);
delete dataset;
delete file;
return 0;
}
I am not from a programming background and have been trying this. If Swandog46 could tell me how to allocate memory on my own I would greatly appreciate it.
