•ptype is a command name specifying the plot type. Executing the command BAR places the command name BAR in PPAR.

•depend is a name specifying a label for the vertical axis. The default value is Y.

A bar is drawn for each element of the column in ΣDAT. Its width is specified by res and its height is the value of the element. The location of the first bar can be specified by indep; otherwise, the value in (xmin, ymin) is used.

Access: …µBAR

BARPLOT

Type:

Command

Description:

Draw Bar Plot Command: Plots a bar chart of the specified column of the current statistics matrix

 

(reserved variable ΣDAT).

 

The data column to be plotted is specified by XCOL and is stored as the first parameter in

 

reserved variable ΣPAR. The default column is 1. Data can be positive or negative, resulting in

 

bars above or below the axis. The y-axis is autoscaled, and the plot type is set to BAR.

 

When BARPLOT is executed from a program, the resulting plot does not persist unless

 

PICTURE, PVIEW (with an empty list argument), or FREEZE is subsequently executed.

Access:

…µBARPLOT

Input:

None

Output:

A bar chart based on ΣDAT.

BASIS

 

Type:

Command

Description:

Determines the basis of a sub-space of the n-space Rn.

Access:

Matrices, !Ø LVECTOR

Input:

A list of vectors defining a vector sub-space of Rn.

Output:

A list containing the vectors of a basis of the vector sub-space.

Flags:

Exact mode must be set (flag –105 clear).

 

Numeric mode must not be set (flag –3 clear).

Example:

Find the vectors that form a basis of the sub-space defined by [1,2,3], [1,1,1], and [2,3,4]

Command:

BASIS({[1,2,3],[1,1,1],[2,3,4]})

Result:

{[1,0,-1],[0,1,2]}

Command

Type:

Description:

Baud Rate Command: Specifies bit-transfer rate.

 

Legal baud rates are 2400, 4800, 9600, 14400, 19200, 38400, 57600 and 115200 (default).
