rsplineΒΆ
rspline computes a rational spline under tension for a given x and y vector.

rmXY = rspline(rvX, rvY, p)

rmXY = rspline(rvX, rvY, p, rsTensionFactor)

rmXY = rspline(rvX, rvY, p, rsTensionFactor, flag)
Return Value
The return value rmXY is a real matrix with two columns. The first column contains the xcoordinates of the spline and the second column contains the ycoordinates of the spline. In case of an error rmXY has only one element with an error number:
1  not enough memory 
2  xcoordinates are not strictly increasing 
3  less than 3 datapoints specified. 
Parameters

rvX
rvX is a real vector with at least 3 elements.

rvY
rvY is a real vector with at least 3 elemetns.

rsTensionFactor
rsTensionFactor is a value in the range 0 to 100. For 0 the spline is similar to a cubic spline and for values close to 100 the result is a polygon. Default value is 1.

p
The meaning of p depends on the value of the parameter flag

flag
flag can be one of the following values:
Value Meaning 1 p is the number of x, ycoordinates calculated. 2 p is the number of x, ycoordinates calculated. The original xcoordinates are added to the total. 3 p is a strictly increasing vector of xcoordinates. Default value is 1.
