Detailed Description

Very convenient class for handling the common problem of having a 2-D grid of data points which you would like to slice through and print out to some file.

In cosmos and cmbcalc wildly used to store and print transfer functions.

Creating a SplineWeb is particularily easy, you just have to provide the size of the grid in x and y directions.

  SplineWeb myWeb(10,20);

Now you can set data points by

  myWeb.set(3,5,1.234);

This will create 10 Splines pointing in Y-Direction and 20 Splines pointing in X-Direction.

Of course, you then are allowed to set 10 data points in Y-direction and 20 Datapoints in X-direction. As the splines are the limiting factor.

For convenience, you just tell the set() routine the real world number, not the index of the spline.

Make sure that these numbers are always the same for each row and collumn:

In other words, for our example, make sure that you do only give 10 different X-Values and only 20 different Y-values.

But as you usually will be filling the grid by a nested loop, no problem here in practice.

void SplineWeb::arm ( )

arm all vectors in the web. If already armed, this will disarm() first..

Spline * SplineWeb::createAlongX ( const double y,

string nombre,

Anchor * a = 0,

Spline * mother = 0

)

Create a spline that hast const y-position y and the direction x return pointer to this new spline. It is your responsibility to delete the spline, if you do not use it anymore... (However, specifyig an anchor will make this easier for you) If mother is null the new spline will own its data, if not, mother (or if itself has a mother then this of course) will be the mother to this spline (i.e. hold the x-data)
