Item
itemNameString
itemNameString,label
Set up a drop-down menu within Custom ...
EndCustm, or ToolBar ... EndTBar blocks. In a
Custom block, specifies the text that is pasted.
In a ToolBar block, specifies the branch label.
Lbl labelName
Define a label with name labelName in a
program. Goto labelName transfers control to
the instruction following labelName. labelName
must meet same requirements as variable
names.
lcm()
(number1,number2)
(list1,list2)
(matrix1,matrix2)
Return the least common multiple of the two
arguments. The LCM of two fractions is the LCM
of the numerators divided by the GCM of the
denominators. The LCM of fractional floating
point numbers is their product.
left()
(sourceString[,num])
Return the leftmost num characters from
sourceString.
(list[,num])
Return the leftmost num elements of list.
(comparison)
Return the left-hand side of the equality or
inequality of comparison.
limit()
(expr,var,point[,direction])
(list,var,point[,direction])
(matrix,var,point[,direction])
Return the limit of the argument expr, list, or
matrix with respect to var at point. The limit is
taken from the left if direction is negative, from
the right if direction is positive, or from both
directions otherwise. The default direction is
both.
Line xStart,yStart,xEnd,yEnd[,mode]
Display Graph screen and draw a line, including
the endpoints, from (xStart,yStart) to (yStart,
yEnd) according to mode:
mode=1: draw the line (default)
mode=0: turn off the line
mode=-1: invert the line
LineHoriz y[,mode]
Display Graph screen and draw a horizontal line
at window coordinate y, according to mode:
mode=1: draw the line (default)
mode=0: turn off the line
mode=-1: invert the line
LineTan expr1,expr2
Display Graph screen and draw line tangent to
expr1 at point x = expr2. The independent
variable for expr1 is x.
LineVert x[,mode]
Display Graph screen and draw a vertical line at
window coordinate x, according to mode:
mode=1: draw the line (default)
mode=0: turn off the line
mode=-1: invert the line
LinReg xlist,ylist[,[freqList],[catlLst],[catincList]]
Calculate linear regression and update all
statistics variables. First four arguments must
be variable names or c1-c99. Last argument
need not be a variable name and cannot be
c1-c99. All lists except catincList must have
equal dimension. The regression equation is
y = a*x + b.
list▶
▶▶
▶mat(list[,rowElements])
Create a matrix whose elements are filled
row-by-row from. rowElements specifies the
number of elements in each matrix row, if used.
The default is one matrix row. If list does not fill
the matrix, zeros are added.
„
„„
„list(list)
Return a list which is the difference between
successive elements of list. Each element of list
is subtracted from the next element, so the
returned list is always one element shorter than
list.
ln()
(expr), (list)
Return the natural logarithm of the argument.
(matrix)
Return the matrix natural logarithm of square
diagonalizable matrix. This is not the same as
finding the logarithm of each matrix element.
