| Description | Xsize-i−1 = Xi, i=0,...,(size−1)/2
The elements of the lower half of a vector are copied in reverse order into the upper half, i.e., the zero'th element is copied to the last, the element number 1 to the second last, and so on. The elements of the first half are not affected by this operation. This function will be used, e.g., to construct a response function for convolutions (see VF_convolve). In this case, note that the zero'th element is to appear only once in the response function and must not be included in the reflection by VF_reflect. Therefore, you have to calculate the response function for size/2+1 elements and to apply reflection from element 1 on. For an example, see VF_convolve. |
