trMatrix-class {Matrix} | R Documentation |
The "trMatrix"
class is the class of triangular
matrices in dense, non-packed storage.
Objects can be created by calls of the form new("trMatrix", ...)
.
uplo
:"character"
. Must be
either "U", for upper triangular, and "L", for lower triangular.diag
:"character"
. Must be
either "U"
, for unit triangular (diagonal is all ones), or
"N"
for non-unit. The implicit diagonal elements are not
explicitly stored when diag
is "U"
.x
:"numeric"
. The numeric
values that constitute the matrix, stored in column-major order.Dim
:"integer"
. The dimensions
of the matrix which must be a two-element vector of non-negative
integers.norm
:"numeric"
. A named
numeric vector of norms of the matrix. Some possible components
are "O"
, the one norm; "I"
, the infinity norm;
"F"
, the Frobenius norm; and "M"
, the maximum
absolute value.rcond
:"numeric"
. A named
numeric vector of reciprocal condition numbers in either the
1-norm "O"
or the infinity norm "I"
.factorization
:"list"
. A named
list of factorizations that have been computed for the matrix.
