get_y_value_funct_1dT_get_y_value_funct_1dGetYValueFunct1dGetYValueFunct1d (Operator)
Name
get_y_value_funct_1dT_get_y_value_funct_1dGetYValueFunct1dGetYValueFunct1d — Return the value of a function at an arbitrary position.
Signature
Herror T_get_y_value_funct_1d(const Htuple Function, const Htuple X, const Htuple Border, Htuple* Y)
Description
get_y_value_funct_1dget_y_value_funct_1dGetYValueFunct1dGetYValueFunct1dGetYValueFunct1d returns the y value of the function
FunctionFunctionFunctionFunctionfunction at the x coordinates specified by XXXXx.
To obtain the y values, the input function is
interpolated linearly. The parameter BorderBorderBorderBorderborder determines the
values of the function FunctionFunctionFunctionFunctionfunction outside of its domain.
For BorderBorderBorderBorderborder='zero'"zero""zero""zero""zero" these values are set to 0, for
BorderBorderBorderBorderborder='constant'"constant""constant""constant""constant" they are set to the
corresponding value at the border, for
BorderBorderBorderBorderborder='mirror'"mirror""mirror""mirror""mirror" they are mirrored at the border,
for BorderBorderBorderBorderborder='cyclic'"cyclic""cyclic""cyclic""cyclic" they are continued
cyclically, and for BorderBorderBorderBorderborder='error'"error""error""error""error" an
exception is raised.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
