XSLP_FUNCEVAL


Description
Bit map for determining the method of evaluating user functions and their derivatives
Type
Integer
Values
Bit
Meaning
3 
evaluate function whenever independent variables change.
4 
evaluate function when independent variables change outside tolerances.
5 
application of bits 3-4: 0 = functions which do not have a defined re-evaluation mode;1 = all functions.
6 
tangential derivatives.
7 
forward derivatives
8 
application of bits 6-7: 0 = functions which do not have a defined derivative mode;1 = all functions.
Default value
0
Notes
Bits 3-4 determine the type of function re-evaluation. If both bits are zero, then the settings for each individual function are used.
If bit 3 or bit 4 is set, then bit 5 defines which functions the setting applies to. If it is set to 1, then it applies to all functions. Otherwise, it applies only to functions which do not have an explicit setting of their own.
Bits 6-7 determine the type of calculation for numerical derivatives. If both bits are zero, then the settings for each individual function are used.
If bit 6 or bit 7 is set, then bit 8 defines which functions the setting applies to. If it is set to 1, then it applies to all functions. Otherwise, it applies only to functions which do not have an explicit setting of their own.
