Questions tagged [stride]

The stride of an array is the number of locations in memory between beginnings of successive array elements, measured in bytes or in units of the size of the array's elements. Arrays may have a stride larger than their elements' width in bytes, which are called a non-unit stride. One particular use of non-unit stride is for images, when creating subimages without copying the pixel data.

Extract every n-th element from TCL list

we can extract every n-th element of a TCL list by foreach loop. But is there a single line generic TCL cmd that will do the trick? Something like lindex with a '-stride' option.
