cssgrid_params - This document briefly describes all the internal
parameters of Cssgrid.
Each entry below includes the name of a parameter, its Fortran
type (use the obvious equivalents for C), its default value, and a short
description of the parameter.
- ´SIG´ - Real - computed
- value of the tension factor for the splines
- ´TOL´ - Real - 0.01
- Tolerance to use in calculating gradient differences to terminate the
iteration sequence when computing global gradients
- ´TTF´ - Real - 0.01
- Tolerance to use in determining how accurately each tension factor should
be calculated to approximate its optimum value
- ´NLS´ - Integer - 10
- Number of nodes to use in the least squares fit.
- ´NSG´ - Integer - 10
- Maximum number of iterations to use in the algorithm for computing
automatic tension factors
- ´ISG´ - Integer - 0
- Flag to revert to calculating automatic tension factors rather than use a
constant tension. Using a constant tension is effected by setting a value
for the control parameter sig. If isg is 0, then a tension array is used,
otherwise a constant tension is used.
- ´IGR´ - Integer - 1
- Flags whether global or local gradients are used (1 implies global,
anything else implies local).
- ´MVL´ - Real - -8.
- Fill value to use in returns for NCL functions. Used only if mvl has been
changed from its default.
