Detailed Description

splint Evaluates the definite integral of a B-spline.

Given the knots and coefficients of a B-spline, evaluate the definite integral of the smoothing polynomial between two given points.

Examples:

  call splrep(x, y, tck=tck, s=0._dp)
  call splint(tck, zero, m_pi / 2._dp, yi) ! yI = 1.000630799770
