setslice
Abstract
Set a slice of an array to a given value
Description
setslice
sets the elements of an array or a slice of it to a given value.
This operation is done in place. It is the equivalent of this code:
array[start:end:step] = value
Syntax
setslice iArray[], ivalue, istart=0, iend=0, istep=1
setslice kArray[], kvalue, kstart=0, kend=0, kstep=1
setslice iArray[], iSource[], istart=0
setslice kArray[], kSource[], kstart=0
setslice SArray[], SSource[], kstart=0
Arguments
value
: the value to set the elements tostart
: the start index of the slice. Defaults to 0end
: the end index of the slice. Defaults to 0 which means until the end of the slicestep
: the number of steps to jump between elements. Default to 1 (all elements in the slice)xSource[]
: the array used as source. In this case, all elements of the source array are copied to the destination array (xArray) starting at the given offset
Output
Execution Time
- Init (if all arguments are of i type)
- Performance (if any argument is of k type)
Examples
iA[] fillarray 0, 1, 2, 3, 4, 5, 6, 7
setslice iA, 0.5 ; will set all elements of iA to 0.5
printarray iA
kB[] init 10
; if the condition is met setslice will set the even indexes
; between 0 to 6 of kB to -1
if kvalue = 1 then
setslice kB, -1, 0, 6, 2
endif
if changed2(kB) == 1 then
printarray kB
endif
; kB: -1, 0, -1, 0, -1, 0, 0, 0, 0, 0
