## vtable1k

vtable1k — Read a vector (several scalars simultaneously) from a table.

## Description

This opcode reads vectors from tables at k-rate.

## Syntax

    vtable1k  kfn,kout1 [, kout2, kout3, .... , koutN ]

## Performance

kfn - table number

kout1...koutN - output vector elements

vtable1k is a reduced version of vtablek, it only allows to access the first vector (it is equivalent to vtablek with kndx = zero, but a bit faster). It is useful to easily and quickly convert a set of values stored in a table into a set of k-rate variables to be used in normal opocodes, instead of using individual table opcodes for each value.

| Note
vtable1k is an unusual opcode as it produces its output on the right side arguments of the opcode.

## Examples

Here is an example of the vtable1k opcode. It uses the files vtable1k.csd.
