VAR is not evaluated and must be a symbol. Assigns the value of FORM to VAR and adds VAR to the list *VARIABLES* of def'ed variables. Returns VAR. If VAR is already bound and the global variable *ASK-ON-REDEFINE* is not nil then you are asked if you want to redefine the variable.
Takes simple or compound data items FIRST, X and Y and returns result of elementswise selecting from X if FIRST is not NIL and from Y otherwise.
Returns a list of consecutive integers from n to m.
Examples:
(iseq 3 7) returns (3 4 5 6 7)
(iseq 3 -3) returns (3 2 1 0 -1 -2 -3)
Returns a list of its arguments
Repeats VALS. If TIMES is a number and VALS is a non-null, non-array atom, a list
of length TIMES with all elements eq to VALS is returned. If VALS is a list and
TIMES is a number then VALS is appended TIMES times. If TIMES is a list of numbers
then VALS must be a list of equal length and the simpler version of repeat is
mapped down the two lists.
Examples:
(repeat 2 5) returns (2 2 2 2 2)
(repeat '(1 2) 3) returns (1 2 1 2 1 2)
(repeat '(4 5 6) '(1 2 3)) returns (4 5 5 6 6 6)
(repeat '((4) (5 6)) '(2 3)) returns (4 4 5 6 5 6 5 6)
Returns a list of NUM equally spaced points starting at A and ending at B.
A can be a list or an array. If A is a list and INDICES is a single number then the appropriate element of A is returned. If is a list and INDICES is a list of numbers then the sublist of the corresponding elements is returned. If A in an array then the number of INDICES must match the ARRAY-RANK of A. If each index is a number then the appropriate array element is returned. Otherwise the INDICES must all be lists of numbers and the corresponding submatrix of A is returned. SELECT can be used in setf.
If SYMBOL is a defined variable it is unbound and removed from the list of defined variables and returns SYMBOL.
Returns a vector with ITEMS as elements.
X is an array or a list. Returns a list of the indices where X is not NIL.
