e^list
Returns a list in which each element is
e
raised to the
power specified by the corresponding element in
list
.

The squareMatrix cannot
have repeated
eigenvalues.
e^squareMatrix
Returns a square matrix that is the matrix exponential
of
squareMatrix
. The matrix exponential corresponds
to the result calculated using power series or Cayley-
Hamilton Theorem techniques. This is
not
the same as
simply calculating the exponential of each element.

The squareMatrix cannot
have repeated
eigenvalues.
eigVc squareMatrix
Returns a matrix containing the eigenvectors for a real
or complex
squareMatrix
, where each column in the
result corresponds to an eigenvalue. The eigenvectors
of a real matrix may be complex. Note that an
eigenvector is not unique; it may be scaled by any
constant factor. TI
-
86 eigenvectors are normalized.
