vvset

vvset

vvset(x, yS, o, d, n)	Create a copy of the vector x and replace the elements o+i*d (i = 0..n-1) with the value ys.
vvset(x, y, o, d)	Create a copy of the vector x and replace the elements o+i*d (i = 0..nrow(y)-1) with the values y[i]

Create a copy of the vector x and replace elements.

Usage 1

vvset(x , y {, o {, d, n}}})

x

source vector

y

replace value

o

starting index, 0 <= o < nrow(x) (default=0)

d

index increment (default=1)

n

number of values to replace (default=nrow(x))

Result 1

The result r is copy of the vector x. All elements r[o+i*d] (i = 0..n-1) are replaced by the value y.

---

Usage 2

vvset(x , y {, o {, d}})

x

source vector

y

replace vector

o

starting index, 0 <= o < nrow(x) (default=0)

d

index increment (default=1)

Result 1

The result r is copy of the vector x. All elements r[o+i*d] (i = 0..nrow(y)-1) are replaced by the value y[i].

The function failes if an index value is out of bounds.

Example:

#a := eval vv(1,2,4,8,16,32)
#b := eval vvget($#a, 0, 2, 3) 
// -> #b = { 1 , 4 , 16 }
#c := eval vvget($#a, 5, -1, 4)
// -> #c = { 32, 16, 8, 4 }
