Returns a new list that is
list2
appended to
the end of
list1
.

augment(
matrix1
;
matrix2
)
⇒
matrix
Returns a new matrix that is
matrix2
appended to
matrix1
. When the “,” character
is used, the matrices must have equal row
dimensions, and
matrix2
is appended to
matrix1
as new columns. When the “;”
character is used, the matrices must have
equal column dimensions, and
matrix2
is
appended to
matrix1
as new rows. Does not
alter
matrix1
or
matrix2
.

h

)
⇒
expression
Returns the forward-difference quotient
(average rate of change).
expression1
can be a user-defined function
name (see
Func
).
h
is the step value. If
h
is omitted, it defaults
to 0.001.
Note that the similar function
nDeriv()
uses
the central-difference quotient.

Bin
⇒
integer
Converts
integer1
to a binary number. Binary
or hexadecimal numbers always have a 0b or
0h prefix, respectively.

Without a prefix,
integer1
is treated as
decimal (base 10). The result is displayed in
binary, regardless of the
Base
mode.
If you enter a decimal integer that is too large
for a signed, 32-bit binary form, a symmetric
modulo operation is used to bring the value
into the appropriate range.
A binary number can have up to
32 digits. A hexadecimal number
can have up to 8.
Zero, not the letter O, followed by b or h.
