Float-array

Change-float-array

Modifying constructor for float-array structures.

Syntax

(change-float-array x 
                    [:components <components>])

This is an often useful alternative to make-float-array.

We construct a new float-array structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by fty::defprod.
