The two Parameter Weibull Distribution

\graph  x=0:4, a=1:4:4, b=1

Example 1

#include <iostream>
#include <codecogs/statistics/distributions/continuous/weibull/cdf.h>
using namespace Stats::Dists::Continuous::Weibull;
 
int main()
{
  std::cout << "CDF(105,20,100) = " << CDF( 105, 20, 100 ) << std::endl;
  return 0;
}
Output:
CDF(105,20,100) = 0.929581
