exp()
Returns the matrix exponential of
squareMatrix1 . This is not the same as
calculating e raised to the power of each
element. For information about the
calculation method, refer to cos() .
squareMatrix1 must be diagonalizable. The
result always contains floating-point
numbers.
exp ► list()
exp ► list( Expr , Var ) ⇒ list
Examines Expr for equations that are
separated by the word " or ," and returns a
list containing the right-hand sides of the
equations of the form Var=Expr . This
gives you an easy way to extract some
solution values embedded in the results of
the solve() , cSolve() , fMin() , and fMax()
functions.
is not necessary with the
Note: exp ► list()
and cZeros() functions because they
zeros()
return a list of solution values directly.
You can insert this function from the
keyboard by typing exp@>list( ... ) .
expand()
expand( Expr1 [, Var ]) ⇒ expression
expand( List1 [, Var ]) ⇒ list
expand( Matrix1 [, Var ]) ⇒ matrix
returns Expr1 expanded
expand( Expr1 )
with respect to all its variables. The
expansion is polynomial expansion for
polynomials and partial fraction expansion
for rational expressions.
The goal of expand() is to transform Expr1
into a sum and/or difference of simple
terms. In contrast, the goal of factor() is to
transform Expr1 into a product and/or
quotient of simple factors.
