ref()

⇒
Matrix1 Tol matrix
ref( [, ])
Returns the row echelon form of Matrix1.
Optionally, any matrix element is treated as zero if its absolute value
is less than Tol. This tolerance is used only if the matrix has floating-
point entries and does not contain any symbolic variables that have
not been assigned a value. Otherwise, Tol is ignored.
/·
• If you use
mode to Approximate, computations are done using floating-
point arithmetic.
If Tol is omitted or not used, the default tolerance is calculated
•
as:

5E 14 max(dim(Matrix1))

Note: rref()

remain()

Value1 Value2
remain( , )
⇒
List1 List2
remain( , )
Matrix1 Matrix2
remain( ,
Returns the remainder of the first argument with respect to the
second argument as defined by the identities:

remain(x,0) x
·
 N
remain(x,y) x y iPart(x/y)
As a consequence, note that
result is either zero or it has the same sign as the first argument.

Note: mod()

Return

Return [ ]
Returns Expr as the result of the function. Use within a
... block.

right()

⇒
List1 Num list
right( [, ])
Returns the rightmost Num elements contained in List1.
If you omit Num, returns all of List1.
