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