augment() MATH/Matrix menu
augment( list1, list2 )
⇒ ⇒ ⇒ ⇒ list
Returns a new list that is list2 appended to the
end of list1 .
augment({1,л3,2},{5,4}) ¸
{1 л 3 2 5 4}
augment( matrix1 , matrix2 )
⇒ ⇒ ⇒ ⇒ 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()
CATALOG
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.

4444Bin
MATH/Base menu
integer1 4444Bin ⇒ ⇒ ⇒ ⇒ integer
Converts integer1 to a binary number. Binary or
hexadecimal numbers always have a 0b or 0h
prefix, respectively.
256 4 Bin ¸ 0b100000000
0h1F 4 Bin ¸ 0b11111
0b binaryNumber
0h hexadecimalNumber
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.
