译者:生物统计家园网 机器人LoveR
描述----------Description----------
A new class for sparse matrices stored in symmetric sparse column format
存储稀疏矩阵的一类新的对称稀疏列格式
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("matrix.ssc", ...).
可以创建对象通过调用的形式new("matrix.ssc", ...)。
插槽----------Slots----------
ra: Object of class numeric, a real array of nnz elements containing the non-zero elements of the lower triangular part of A, stored in column order. Thus, if i<j, all elements of column i precede elements from column j. The order of elements
ra:对象的类numeric,一个真正的数组NNZ元素包含非零元素的下三角部分A,存储在列的顺序。因此,如果I <J,第i列第j列元素之前的所有元素。元素的顺序
ja: Object of class integer, an integer array of nnz elements containing the row
ja:对象的类integer,一个整数数组NNZ元素包含行
ia: Object of class integer, an integer array of n+1 elements containing pointers to the beginning of each column in the arrays "ra" and "ja". Thus "ia[i]" indicates the position in the arrays "ra" and "ja" where the ith column begins. The last, (n+1)st, element of "ia" indicates where the n+1 column would start, if it existed.
ia:对象的类integer,一个整数数组中的n +1个元素阵列的Ra“和”JA“中的每一列包含指针的开始。因此IA [i]的表示的阵列岭和ja的,其中开始的第i列中的位置。最后,(N +1)日,元素的“IA”表示,其中N +1列开始,如果它存在。
dimension: Object of class integer, dimension of the matrix
dimension:对象类integer,维数的矩阵
