Class Histogram
Class Histogram allows the easy compilation of distribution statistics. To show how to use this class, here is a brief example which employs the uniform random number generator as a source of random deviates:
 
#include <rw/histo.h>
#include <rw/rand.h>
#include <iostream>
int main()
{
RWTRandUniform<RWRandGenerator> ru;
// Vector of 100 random points:
RWMathVec<double> v(100,ru);
/*
* Construct a histogram with 10 bins,
* encompassing the data in v.
* This will also initialize the histogram
* with the data in v.
*/
Histogram hg(10, v);
// Print the results:
std::cout << hg << "\n";
}
Note that the counts in class Histogram are in a public RWMathVec<int> base class; it can be used anywhere an integer vector can be used:
 
Histogram hg1;
Histogram hg2;
.
. // Fill up hg1 and hg2.
.
// Calculate and print the sum of the two histograms:
std::cout << hg1 + hg2;
