randumat
Generate random uncertain umat
objects
Syntax
um = randumat(ny,nu) um = randumat
Description
um = randumat(ny,nu)
generates an uncertain matrix of size ny-by-nu
. randumat
randomly selects from uncertain atoms of type 'ureal'
, 'ultidyn'
, and 'ucomplex'
.
um = randumat
results in a 1-by-1 umat
uncertain object, including up to four uncertain objects.
Examples
The following statement creates the umat
uncertain object x1
of size 2-by-3. Note that your result can differ because a random seed is used.
x1 = randumat(2,3)
x1 = Uncertain matrix with 2 rows and 3 columns. The uncertainty consists of the following blocks: AWYRT: Uncertain real, nominal = 7.09, variability = [-7.84,16.4]%, 2 occurrences HRRED: Uncertain complex, nominal = 3.14+5.47i, radius = 1.92, 1 occurrences VSIYA: Uncertain real, nominal = -4.05, variability = [-1.53,3.83], 3 occurrences YZEZY: Uncertain complex, nominal = -6.54-2.17i, variability = 24%, 1 occurrences Type "x1.NominalValue" to see the nominal value, "get(x1)" to see all properties, and "x1.Uncertainty" to interact with the uncertain elements.
The following statement creates the umat
uncertain object x2
of size 4-by-2 with the seed 91.
rng(91,'twister'); x2 = randumat(4,2)
x2 = Uncertain matrix with 4 rows and 2 columns. The uncertainty consists of the following blocks: YQZBI: Uncertain complex, nominal = 3.61+1.88i, radius = 1.42, 1 occurrences Type "x2.NominalValue" to see the nominal value, "get(x2)" to see all properties, and "x2.Uncertainty" to interact with the uncertain elements.
