>
randPoly(Va r, Order) ⇒ expression
Returns a polynomial in Va r of the specified Order. The coefficients
are random integers in the range
L9 through 9. The leading
coefficient will not be zero.
Order must be 0–99.
randSamp()
Catalog
>
randSamp(List,#Trials[,noRepl]) ⇒ list
Returns a list containing a random sample of #Trials trials from List
with an option for sample replacement (noRepl=0), or no sample

>
RandSeed Number
If Number = 0, sets the seeds to the factory defaults for the random-
number generator. If Number ƒ 0, it is used to generate two seeds,
which are stored in system variables seed1 and seed2.
real()
Catalog
>
real(Va lu e 1) ⇒ value
Returns the real part of the argument.
real(List1) ⇒ list
Returns the real parts of all elements.
real(Matrix1) ⇒ matrix
Returns the real parts of all elements.

You can insert this operator from the computer keyboard by
typing @>Rect.
Displays Ve ct or in rectangular form [x, y, z]. The vector must be of
dimension 2 or 3 and can be a row or a column.

not update ans.
