e^ list
Returns a list in which each element is
power specified by the corresponding element in list.
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.
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.
eigVl squareMatrix
Returns a list of the eigenvalues of a real or complex
squareMatrix. The eigenvalues of a real matrix may be
complex.
