PURGE Purges the named variables or empty subdirectories from
the current directory.
PUT Replaces the object at a specified position in an array.
PUTI As for PUT (see above) but also increments the position.
PVAR Calculates the population variance of the coordinate
values in each of the m columns in Σ DAT .
PVARS Returns a list of the backup objects and library objects in a
specified port, and the available memory.
Displays PICT with the specified coordinates at the upper
PVIEW
left corner of the graphics display.
Stores PWRFIT in Σ PAR , so that subsequent executions
PWRFIT
of LR use the power curve fitting model.
PX→C Converts the specified pixel coordinates to user-unit
coordinates.
→Q
Returns a rational form of the argument.
QR Returns the QR factorization of an m × n matrix.
QUAD Finds zeros of an expression equated to 0, or solves an
equation. Same as SOLVE.
