Uncertain matrices (class
are built from doubles and uncertain elements, using traditional MATLAB® matrix
building syntax. Uncertain matrices can be added, subtracted, multiplied,
inverted, transposed, etc., resulting in uncertain matrices. The rows
and columns of an uncertain matrix are referenced in the same manner
that MATLAB references rows and columns of an array, using parenthesis,
and integer indices. The
NominalValue of a uncertain
matrix is the result obtained when all uncertain elements are replaced
with their own
NominalValue. The uncertain elements
making up a
umat are accessible
Uncertainty gateway, and the properties
of each element within a

values may be substituted for any of the uncertain elements within
umat. The command
a random sample of the uncertain matrix, substituting random samples
(within their ranges) for each of the uncertain elements.
tight bounds on the worst-case (maximum over the uncertain elements'
ranges) norm of the uncertain matrix.
Standard MATLAB numerical matrices (i.e.,
naturally can be viewed as uncertain matrices without any uncertainty.
