SCALE Syntax: SCALE(matrix, value, rownumber)
Multiplies the specified row_number of the specified
matrix by value.
SCALEADD Syntax: SCALEADD (matrix, value, row1, row2)
Multiplies the specified row1 of the matrix by value,
then adds this result to the second specified row2 of the
matrix and replaces row1 with the result.
SUB Syntax: SUB (matrix, start, end)
Extracts a sub-object—a portion of a list, matrix, or
graphic—and stores it in matrix. Start and end are each
specified using a list with two numbers for a matrix, a
number for vector or lists, or an ordered pair, (X,Y), for
graphics: SUB(M1{1,2},{2,2})
SWAPCOL Syntax: SWAPCOL (matrix, column1, column2)
Swaps column1 and column2 of the specified matrix.
SWAPROW Syntax: SWAPROW(matrix, row1, row2)
Swaps row1 and row2 in the specified matrix.
App Functions
These commands allow you to launch any HP app, bring
up any view of the current app, and change the options in
the View menu.
STARTAPP Syntax: STARTAPP("name")
Starts the app with name. This will cause the app
program’s START function to be run, if it is present. The
app’s default view will be started. Note that the START
function is always executed when the user taps in
the Application Library. This also works for user-defined
apps.
Example: STARTAPP("Function") launches the Function
app.
STARTVIEW Syntax: STARTVIEW( [,draw?])
