Description

sample_funct_1dsample_funct_1dsample_funct_1dSampleFunct1dSampleFunct1d samples the input function FunctionFunctionFunctionFunctionfunction in the interval [XMinXMinXMinXMinXMin,XMaxXMaxXMaxXMaxXMax] at equidistant points with the distance XDistXDistXDistXDistXDist. The last point lies in the interval if XMaxXMaxXMaxXMaxXMax-XMinXMinXMinXMinXMin is not an integer multiple of XDistXDistXDistXDistXDist. To obtain the samples, 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, and for BorderBorderBorderBorderborder='cyclic'"cyclic""cyclic""cyclic""cyclic" they are continued cyclically.
