ncl_cssgrid_params - Man Page

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.
