描述----------Description----------

The "dtrMatrix" class is the class of triangular, dense, numeric matrices in nonpacked storage.  The "dtpMatrix" class is the same except in packed storage.
"dtrMatrix"类是类三角形，密集，在nonpacked存储数字矩阵。 类"dtpMatrix"是相同的，除了在包装存储。


类的对象----------Objects from the Class----------

Objects can be created by calls of the form new("dtrMatrix", ...).
创建对象可以通过电话的形式new("dtrMatrix", ...)。


插槽----------Slots----------




uplo: Object of class "character". Must be
uplo类"character"的对象。必须




diag: Object of class "character". Must be either "U", for unit triangular (diagonal is all ones), or
diag类"character"的对象。必须是"U"（是对角线的）为单元的三角形，或




x: Object of class "numeric". The numeric
x类"numeric"的对象。数字




Dim: Object of class "integer". The dimensions of the matrix which must be a two-element vector of non-negative
Dim类"integer"的对象。它必须是一个非负的两个元素的向量矩阵的尺寸


延伸----------Extends----------

Class "ddenseMatrix", directly. Class "triangularMatrix", directly. Class "Matrix" and others, by class "ddenseMatrix".
类"ddenseMatrix"，直接。类"triangularMatrix"，直接。类"Matrix"类"ddenseMatrix"和其他。

(T &lt;- as(M, "dtrMatrix")) ## upper triangular is default[＃上三角是默认]
(T2 <- as(t(M), "dtrMatrix"))
stopifnot(T@uplo == "U", T2@uplo == "L", identical(T2, t(T)))
