- FITZ fits smooth curves to a surface of data points.
- e.g. Given some data points, e.g.
-
- x y z
- ---- data file testf.dat -----
- 1 1 1
- 1 2 1
- 2 2 1
- 2 1 1
- 1.5 1.5 2
- ------------------------------
-
- These points defile the for corners of a surface which has
- one high point in the center. As you can see the order of
- points is not relevant.
-
- It is important that each line of the data file has three
- points on it. (x, y, z)
-
- FIT then asks you for a range of x and y values generate z values
- for. The range is given as minimum,maximum,stepsize.
- e.g. 1,3,.5 would produce 1, 1.5, 2, 2.5, 3
-
- Use SURF to draw the surface on the screen and see the finished
- product.
-
- $ FITZ
- Data file conaining x y z data ? TESTF.DAT
- Read 5 points from file {testf.dat}
- Will write data to {testf.z}
- Number of points to use for contouring each point ? [3]
- Range of output x values [1,2,6.666667e-02] ? 1,2,.05
- Range of output y values [1,2,6.666667e-02] ? 1,2,.05
- nx 21, ny 21, Work space iwk=2384 bytes wk=160 bytes
- Y = 1 1.05 1.1 1.15 1.2 1.25 1.3 1.35 1.4 1.45 1.5 1.55 1.6 1.65
- 1.7 1.75 1.8 1.85 1.9 1.95 2

- Now use TESTF.Z as your data file for SURFACE.
