Entry Format
Explanation
Screen
1:seq seq(expression, var, low,high [,step]) Returns a sequence of values.
Sequence begins at "low"
and runs through "high".
The default for the step is 1.
2:min min(expression1, expression2)
min(list1,list2)
min(matrix1,matrix2)
Returns the minimum of two
arguments.
3:max max(expression1, expression2)
max(list1,list2)
max(matrix1,matrix2)
Returns the maximum of two
arguments.
4:SortA listName1[,listName2],... Sorts the elements of the first
argument in ascending order.
The list must be named first;
then sort the list; then you
can display the list.
5:SortD listName1[,listName2],... Same as SortA, except that
SortD sorts in descending order.
6:sum sum(list) Returns the sum of the list.
This can also be used to find
the sum of a sequence.
7:cumSum cumSum(list) Returns a list of the cumulative
sums of the arguments in the list.
It begins at the first element.
8:product product(list) Returns the product of the
elements in the list.
9:left

left(sourceString [,num])
left(list1 [,num])
left(comparison)

Returns the leftmost "num" of
characters in a string. The default
is the entire string.
The " key is .
A:mid mid(sourceString,start [,count])
mid(sourceList,start [,count])
Returns "count" characters from
the list, beginning with element
number start.
B:right right(list1 [ ,num]) Returns the rightmost "num"
characters in the list1.
C:polyEval polyEval(list1,expression1
polyEval(list1,list2)
Interprets the first argument as the
coefficient of a polynomial.
The degrees should be descending.
Returns the polynomial evaluated
for the value of the second argument.
D:list>mat list>mat(list [,elementsPerRow]) Returns a matrix filled row by row
with the elements in the list. The
default for "elementsPerRow" is
the number of elements in list.
E:mat>list mat>list(matrix) Returns a list filled with the elements
in "matrix". The elements are copied
row by row.
