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 <itcomm.h>
    #include <itmex.h>

    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_45 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]);
    }
