sample_funct

sample_funct_1d ( : : Function, XMin, XMax, XDist, Border : SampledFunction )

Sample a function equidistantly in an interval.

sample_funct_1d samples the input function Function in the interval [XMin,XMax] at equidistant points with the distance XDist. The last point lies in the interval if XMax-XMin is not an integer multiple of XDist. To obtain the samples, the input function is interpolated linearly. The parameter Border determines the values of the function Function outside of its domain. For Border='zero' these values are set to 0, for Border='constant' they are set to the corresponding value at the border, for Border='mirror' they are mirrored at the border, and for Border='cyclic' they are continued cyclically.

Parameters

`Function` (input_control)	function_1d-array `->` real / integer
Input function.

`XMin` (input_control)	number `->` real / integer
Minimum x value of the output function.

`XMax` (input_control)	number `->` real / integer
Maximum x value of the output function.
Restriction: `XMax > XMin`

`XDist` (input_control)	number `->` real / integer
Distance of the samples.
Restriction: `XDist > 0`

`Border` (input_control)	string `->` string
Border treatment for the input function.
Default value: 'constant'
List of values: 'zero', 'constant', 'mirror', 'cyclic'

`SampledFunction` (output_control)	function_1d-array `->` real
Sampled function.

Parallelization Information

sample_funct_1d is reentrant and processed without parallelization.
