augment() MATH/Matrix menu
augment(list1, list2) ⇒ list
Returns a new list that is list2 appended to
the end of list1.

}
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.
avgRC(f(x),x,h) ¸
f(x+h) - f(x)

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