e^(squareMatrix1)
Returns the matrix exponential of
squareMatrix1
calculating e raised to the power of each
element. For information about the
calculation method, refer to
squareMatrix1
result always contains floating-point
numbers.
eigVc()
MATH/Matrix menu
eigVc(squareMatrix)
Returns a matrix containing the eigenvectors
for a real or complex
each column in the result corresponds to an
eigenvalue. Note that an eigenvector is not
unique; it may be scaled by any constant
factor. The eigenvectors are normalized,
meaning that if V = [x
x + x

transformations until the row and column
norms are as close to the same value as
possible. The
upper Hessenberg form and the eigenvectors
are computed via a Schur factorization.
eigVl()
MATH/Matrix menu
eigVl(squareMatrix)
Returns a list of the eigenvalues of a real or
complex
squareMatrix
transformations until the row and column
norms are as close to the same value as
possible. The
upper Hessenberg form and the eigenvalues
are computed from the upper Hessenberg
matrix.
