DrawSeqEtrCon, DrawSeqEtrPlt

I/O - Draw

Syntax: DrawSeqEtrCon

DrawSeqEtrPlt

Function: Graphs a recursion expression whose vertical axis is Σan (Σbn or Σcn) and whose horizontal axis is n using a generated number table, in accordance with the conditions of each command.

Description: DrawSeqEtrCon draws a connect type graph, while DrawSeqEtrPlt draws a plot type graph.

DrawShade

I/O - Draw

Syntax: DrawShade<expression 1>, <expression 2>[, <number 1>, <number 2>][,<color command>]

Function: Shades the area between expression 1 (lower curve) and expression 2 (upper curve) from x-values of number 1 to number 2.

Description: Expression 1 and expression 2 have a y= type expression on the right side. Graphing of any other type of expression is not supported by this command.

DrawStat

I/O - Draw

Syntax: DrawStat

 

Function: Draws a statistical graph.

ExpReg (ExpR)

Misc - Statistics(1) - Regression

Syntax: ExpRegxList, yList[,[FreqList (or 1)][, [<yn>] [,{On ; Off}]]]

Function: Performs y = a·eb·x regression.

Description: See SinReg.

ExpToStr

Misc - String(1)

Syntax: ExpToStr<expression>,<storage variable name>

Function: Converts the result of an input expression to a string and assigns the string to the specified variable.

F

FCD

k

Syntax: FCDLower value, Upper value, n:df value,

d:df value

Function: See “F Cumulative Distribution” (page 146).

FPD

k

Syntax: FPDx value, n:df value, d:df value

Function: See “F Probability Density” (page 146).

For~To~(Step~)NextCtrl - For

Syntax:

For<expression 1>⇒<control variable name> To<expression 2> [Step<expression 3>] [<statement>] … : Next

•<expression 1> is the initial value, <expression 2> is the end value, and <expression 3> is the step.

Function: Anything between the For command and the Next command is repeated for a count starting with the initial value of the control variable and ending when the control variable reaches the end value. Each pass causes the value of the control variable to be changed by the value specified by the step value. The loop is terminated whenever the control variable value exceeds the end value.

Description:

•1 is used for the step if a step value is not specified.

•The initial value can be less than the end value, as long as a positive value is specified for the step. In this case, the value of the control value is increased by the step with each pass.

•The initial value can be greater than the end value, as long as a negative value is specified for the step. In this case, the value of the control value is decreased by the step with each pass.

•You can use a multi-statement command (:) in place of the carriage return to separate statements.

•Do not use the Goto command to exit a For~Next loop.

G

GeoCD

k

Syntax: GeoCDLower value, Upper value, pos value

Function: See “Geometric Cumulative Distribution” (page 147).

GeoPD

k

Syntax: GeoPDx value, pos value

Function: See “Geometric Distribution Probability” (page 147).

GetFolderMisc - Variable - Folder

Syntax: GetFolder<storage variable name>

Function: Gets the current folder name and assigns it to a variable as a text string.
