15.5.634 tense

tense(x, y, xf [, tension][, dlhs, drhs])

Interpolates functions using splines under tension, and returns the y-coordinates of the interpolated points. The input points have coordinates (x, y) (arrays), and x must be in ascending order. The interpolation is performed at x coordinates xf. tension governs the tenseness of the interpolation curve. It defaults to 1 and must not be smaller. dlhs and drhs are the desired first derivatives at the left-hand and right-hand sides, respectively.
