Detailed Description

Conversions between IT++ and Matlab for writing mex-files.

Author
Tony Ottosson and Pal Frenger

These routines are used to help writng mex-files for speeding up matlab simulations. A simple mex-file that performs QPSK modulation is given below.

#include <itpp/itcomm.h>
#include <itpp/itmex.h>
using namespace itpp;
void mexFunction(int n_output, mxArray *output[], int n_input, const mxArray *input[])
{
// Check the number of inputs and output arguments
if(n_output!=1) mexErrMsgTxt("Wrong number of output variables!");
if(n_input!=1) mexErrMsgTxt("Wrong number of input variables!");
// Convert input variables to IT++ format
bvec input_bits = mxArray2bvec(input[0]);
// ------------------ Start of routine ---------------------------
cvec output_symbols;
QPSK qpsk;
output_symbols = qpsk.modulate_bits(input_bits);
// ------------------ End of routine -----------------------------
// Create output vectors
output[0] = mxCreateDoubleMatrix(1,output_symbols.size(), mxCOMPLEX);
// Convert the IT++ format to Matlab format for output
cvec2mxArray(output_symbols, output[0]);
}
