CC_PROJECT
Clenshaw-Curtis-Like Quadrature for Semi-Infinite and Infinite Intervals


CC_PROJECT is a MATLAB library which investigates the extension of a Clenshaw-Curtis-like quadrature scheme to semi-infinite and infinite intervals, and to integrands with a specified density function.

The Legendre integral for f(x) is:

        I(f) = integral ( -1 <= x <= +1 ) f(x) dx
      
Quadrature rules for the Legendre integral include:

The Laguerre integral for f(x) is:

        I(f) = integral ( 0 <= x <= +oo ) f(x) rho(x) dx
      
Depending on the value of the density function rho(x) we have: Quadrature rules include:
