• This example shows how to generate sine signal:

  
  // isip include files
  //
  #include <Generator.h>
  	 
  // main program starts here
  //
  int main(int argc, const char **argv) {
  
    // declare a generator
    //
    Generator gen;
  
    // set signal type to be sine   
    //
    gen.setAlgorithm(Generator::SINE);
  
    // set sample frequency
    //
    gen.setSampleFrequency(40);
  
    // set frame duration
    //
    gen.setFrameDuration(1);
         
    // set amplitude
    //
    gen.setAmplitude(1);
  
    // set frequency
    //
    gen.setFrequency(4);
            
    // create a pseudo input vector
    //
    VectorFloat input;
     
    // compute the signal output
    //
    VectorFloat output;
    gen.compute(output, input);
  
    // print the input, the output and the generator object to the console
    //
    input.debug(L"input:");
    gen.debug(L"generator:");
    output.debug(L"output:");
     
    // exit gracefully
    //
    Integral::exit();
  }

  
  
• This example shows how to generate gaussian noise:

  
  // isip include files
  //
  #include <Generator.h>
  	 
  // main program starts here
  //
  int main(int argc, const char **argv) {
  
    // declare a generator
    //
    Generator gen;
  
    // set signal type to be gaussian   
    //
    gen.setAlgorithm(Generator::GAUSSIAN);
  
    // set the mean and the variance of the gaussian noise
    //
    gen.setMean(1.5);
    gen.setVariance(-0.5);
  
    // seed the random number generator
    //
    gen.setSeed(80);
    
    // set other parameters
    //
    gen.setSampleFrequency(40);
    gen.setFrameDuration(1);
    gen.setSignalDuration(1);
           
    // create a pseudo input vector
    //
    VectorFloat input;
    
    // compute the signal output
    //
    VectorFloat output;
    gen.compute(output, input);
  
    // print the input, the output and the generator object to the console
    //
    input.debug(L"input:");
    gen.debug(L"generator:");
    output.debug(L"output:");
     
    // exit gracefully
    //
    Integral::exit();
  }

  
  
• This example shows how to generate a Lorentz time series:

  
  // isip include files
  //
  #include <Generator.h>
  	 
  
  int main() {
  
    VectorFloat test_generation, dummy;
  
    // declare a generator
    //
    Generator gen1;
  
    // Set the type and parameters for the Lorentz system
    //
    gen1.set(Generator::LORENTZ);
    gen1.setSampleFrequency((float)100);
    gen1.setGenSampleFrequency((float)100);
    gen1.setSignalDuration(1);
    gen1.setFrameDuration(1);
    gen1.setLorentz((float)0.15, (float)0.2, (float)10, (float)0.5, 
                    (float)0.5 , (float)0.5, (float)0.5);
    gen1.compute(test_generation, dummy);
  
  
    // exit gracefully
    //
    Integral::exit();
  
  }
