used to generate the two system variables
seed1 and seed2.
RclGDB GDBvar
Restore all Graph database settings from the
variable GDBvar. See StoGDB for the settings.
RclPic picVar[,row,column]
Display Graph screen and add the picture
picVar at the upper-left corner coordinates of
(row,column), by logically OR-ing picVar with
the Graph screen. The default coordinates are
(0,0).
real()
(expr), (list), (matrix)
Return the real part of expr, or the real parts of
the elements of list or matrix. Undefined
variables are treated as real. See also imag().
▶
▶▶
▶Rect
vector ▶Rect
Display vector in rectangular form [x,y,z]. vector
must be a row or column vector with dimension
2 or 3. Rect can only be used at the end of an
entry line and does not update ans.
complexValue ▶Rect
Display complexValue in rectangular for a + bi.
complexValue may have any form, but an re
iθ
entry causes an error in Degree mode. For polar
entries the form (r∠θ) must be used.
ref(matrix[,tol])
Return the row echelon form of matrix. Treat
any element as zero if it is less than tol, and the
matrix contains floating-point elements and no
symbolic elements. The default tol is 5E-14 *
max(dim(matrix)) * rowNorm(matrix).
Floating-point arithmetic is used in Approx
mode.
remain()
(expr1,expr2), (list1,list2), (matrix1,matrix2)
Return the remainder of the first argument with
respect to the second argument as
remain(x,0) = x
remain(x,y) = x-y*iPart(x/y)
Note that remain(-x,y) = -remain(x,y).
Rename oldVarName,newVarName
Rename variable oldVarName as newVarName.
Request promptString,var
If used inside a Dialog...EndDlog structure,
create a user input box in the dialog box,
otherwise create a dialog box with the input box.
promptString must be less than 21 characters. If
var contains a string, it is displayed as the
default.
Return [expression]
Exit a program or function if no argument used,
otherwise return expression from a function.
right()
(list[,num])
Return the rightmost num elements of list.
Return list if num not used.
(string,[num])
Return the rightmost num characters of string.
Return string if num not used.
(comparison)
Return the right side of equation or inequality.
rotate()
(integer,[n])
Rotate signed 32-bit integer n bits. Rotate to the
left if n is positive, to the right if n is negative.
Default n is -1.
(list,[n])
Return list with elements rotated by n elements.
Rotate to the left for positive n, to the right for
negative n. Default n is -1.
(string,[n])
Return string with characters rotated by n
characters. Rotate to the left for for positive n, to
the left for negative n. Default n is -1.
round()
(expr[,d]), (list[,d]), (matrix[,d])
Return argument elements rounded to d digits
after the decimal point. d must be an integer in
the range 0-12. Default d is 12.
rowAdd(matrix,r1,r2)
Return matrix with row r1 replaced by the sum
of rows r1 and r2.
rowDim(matrix)
Return number of rows of matrix.
