描述----------Description----------
The classes "mpfrMatrix" and "mpfrArray" are, analogously to the base matrix and array functions and classes simply “numbers” of class mpfr with an additional Dim and Dimnames slot.
类"mpfrMatrix"和"mpfrArray"是，类似于basematrix和array函数和类的简单的“数字”之类的mpfr一个额外的Dim和Dimnames插槽。
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("mpfrMatrix", ...) or new("mpfrArray", ...), or also by dim(x) <- dd or t(x) where x is a an mpfr “number vector”.
可以创建对象通过调用的形式new("mpfrMatrix", ...)或new("mpfrArray", ...)，也由dim(x) <- dd或t(x)其中x是一个mpfr＆ldquo数矢量“。
A (slightly more) alternative to dim(x) <- dd is mpfr2array(x, dd, dimnames).
A（略多）替代dim(x) <- dd是mpfr2array(x, dd, dimnames)。
插槽----------Slots----------
.Data: as for the mpfr class, a
.Data：mpfr类，
Dim: of class "integer", specifying the array
Dim：类"integer"中，指定数组
Dimnames: of class "list" and the same length as Dim, each list component either NULL or a
Dimnames：类"list"和相同长度的Dim，每个列表组件是NULL或
扩展----------Extends----------
Class "mpfrMatrix" extends "mpfrArray", directly.
类"mpfrMatrix" "mpfrArray"，直接延伸。
Class "mpfrArray" extends class "mpfr", by class "mpfrArray", distance 2; class "list", by class "mpfrArray", distance 3; class "vector", by class "mpfrArray", distance 4.
类"mpfrArray"扩展类"mpfr"，类的“mpfrArray”，距离2类"list"，由类“mpfrArray”，距离3类"vector"，类的“mpfrArray”，距离4。

%*% signature(x = "mpfr", y = "mpfrMatrix"): Compute the matrix/vector product x y when the dimensions (dim) of x and y match.
