HP 48GII User Manual

Full Command and Function Reference 3-19
To use a library object, it must be in a port and it must be attached. A library object copied into
RAM (such as through the PC Link) must be stored into a port using STO.
Some libraries require you to ATTACH them.
You can ascertain whether a library is attached to the current directory by executing LIBS.
The number of libraries that can be attached to the HOME directory is limited only by the
available memory. However, only one library at a time can be attached to any other directory. If
you attempt to attach a second library to a non-HOME directory, the new library will overwrite
the old one.

CAS: Concatenate lists, or vectors, with elements, or create matrices from row vectors.
AUTO
Type: Command
Description: Autoscale Command: Calculates a y-axis display range, or an x- and y-axis display range.
The action of AUTO depends on the plot type as follows:
Plot Type Scaling Action
FUNCTION Samples the equation in EQ at 40 values of the independent
variable, equally spaced through the x-axis plotting range, discards
points that return ±∞, then sets the y-axis display range to include
the maximum, minimum, and origin.
CONIC Sets the y-axis scale equal to the x-axis scale.
POLAR Samples the equation in EQ at 40 values of the independent
variable, equally spaced through the plotting range, discards points
that return ±∞, then sets both the x- and y-axis display ranges in
the same manner as for plot type FUNCTION.
PARAMETRIC Same as POLAR.
TRUTH No action.
BAR Sets the x-axis display range from 0 to the number of elements in
ΣDAT, plus 1. Sets the y-range to the minimum and maximum of
the elements. The x-axis is always included.
HISTOGRAM Sets the x-axis display range to the minimum and maximum of the
elements in ΣDAT. Sets the y-axis display range from 0 to the
number of rows in ΣDAT.
