描述
sample_funct_1dsample_funct_1dSampleFunct1dSampleFunct1dSampleFunct1dsample_funct_1d samples the input function FunctionFunctionFunctionFunctionfunctionfunction
in the interval [XMinXMinXMinXMinXMinxmin,XMaxXMaxXMaxXMaxXMaxxmax] at equidistant points
with the distance XDistXDistXDistXDistXDistxdist. The last point lies in the
interval if XMaxXMaxXMaxXMaxXMaxxmax-XMinXMinXMinXMinXMinxmin is not an integer multiple
of XDistXDistXDistXDistXDistxdist. To obtain the samples, the input function is
interpolated linearly. The parameter BorderBorderBorderBorderborderborder determines the
values of the function FunctionFunctionFunctionFunctionfunctionfunction outside of its domain.
For BorderBorderBorderBorderborderborder='zero'"zero""zero""zero""zero""zero" these values are set to 0, for
BorderBorderBorderBorderborderborder='constant'"constant""constant""constant""constant""constant" they are set to the
corresponding value at the border, for
BorderBorderBorderBorderborderborder='mirror'"mirror""mirror""mirror""mirror""mirror" they are mirrored at the border,
and for BorderBorderBorderBorderborderborder='cyclic'"cyclic""cyclic""cyclic""cyclic""cyclic" they are continued
cyclically.
