matrix
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
.

avgRC()

avgRC(
expression1
,
var
[
,
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.
