make-rand om-state 334
I
: extension
The amount by which to extend the plane. See the section "Planes"
in Symbolics Common Lisp: Language Concepts.
: initial-dimensions
A list of dimensions for the initial creation of the plane. You might
want to use this option to create a plane whose ill"st dimension is a
multiple of 32, so you can use bitblt on it. The default is 1 in each
dimension.
: initial-origins
A list of origins for the initial creation of the plane. The default is
all zero.
Example:
(make-plane 2 :type sys:art-4b :default-value 3)
creates a two-dimensional plane of type sys:art-4b, with default value 3.
make-random-state &optional state Function
Returns a new object of type random-state which the function random can
use as its state argument.
If state is nil or omitted, make-random-state returns a copy of the current
random-number state object (the value of variable *random-state*).
If state is a state object, a copy of that state object is returned.
If state is t, the function returns a new state object that has been
"randomly" initialized.
Examples:
(setq x (make-random-state» => #.(RANOOM-STATE 71 16954B6379 ... )
;;; the value of x is now a random state
(setq copy-x (make-random-state x» => #.(RANOOM-STATE 71 ... )
;;; this makes a copy of random state x
;;; a way to get reproducibly random numbers

make-raster-array width height &key make-array-options Function
Makes rasters; this should be used instead of make-array when making arrays
that are rasters. make-raster-array is similar to make-array, but
make-raster-array takes width and height as separate arguments instead of
taking a single dimensions argument. If the raster is to be used with
bitblt, the width times the number of bits per array element must be a
multiple of 32.
