Name (keyboard access) Description
RKFERR (Ssove FTAEETA) Estimate absolute
error for given step when solving initial-value differential
equation, via Runge-Kutta-Fehlberg, given (right-hand
side of) equation and names of variables.
REFSTER (rsove (EFEAEEE) Find next Runge-
Kutta-Fehlberg solution stzep of initial-value differential
equation, given variable names, step, ., and tolerance.
RL (MTH) Rotate left 1 bit.
FLE (e IEEEE ) SN Rotate left 1 byte.
RMO (vrH) T 7<) IEGT) Round value ton
decimal places (for 0 < n < 11); or to n significant digits
(for n < 0); or to current display setting (for n = 12).
RHEM (vrH) EFAMEEICETIEE) Row norm of array.
ROLL (()sTack)IGTTMM) Rotate the contents of the bot-
tom n levels of the stack (after consuming argument »)
by rolling each obj up a level (except for obj, , which goes
to level 1).
FOLLD (qrsTack)[TMM]) Rotate the contents of the
bottom n levels of the stack (after consuming argument
n) by rolling each obj down a level (except for obj,, which
goes to level n).
ROOT (sove IATIRIETER) Find root value of given
variable—i.e. that which gives result nearest zero in the
given prgm or expr, starting with the given guess(es).
FOT (lsTack) ICITEM) Rotate the contents of the bot-
tom 3 levels of the stack by rolling each obj up a level
(except for obj ., which goes to level 1).
+ROW (m Decompose given
array into rows, placing rows in order on the stack, fol-
lowed by the row count. Vectors are treated as column
matrices.
ROk+ () (EEREA I ) Insert array, into
array,, beginning at indicated position.
ROW- (v7r) EEHANTEE TS Delete row n from
given array,; return resulting array, and deleted row,.
ROk (vmh) IR ETTRERT) Build array from n
given rows. Vectors are treated as column matrices.
RR (vr) EEEE ) I EETE) Rotate right 1 bit.
RRE (u7H EEE ) EEREETE) Rotate rt. 1 byte.
FREF (vTh EEHARIRRERER) Convert a (square)
matrix 10 its reduced row echelon form.
