copya2ftab

The copya2ftab opcode takes a k-array and copies the contents to an f-table.

Syntax

copya2ftab(kArray[], ktab [, koffset])
copya2ftab(iArray[], itab [, ioffset])

copya2ftab kArray[], ktab [, koffset]
copya2ftab iArray[], itab [, ioffset]

Performance

kArray[] -- one-dimensional array for source.

ktab -- f-table for destination.

koffset -- offset into the f-table (defaults to 0).

Examples

Here is an example of the copya2ftab opcode. It uses the file copya2ftab-modern.csd.
