描述----------Description----------
A new class for sparse matrices stored in symmetric sparse row format
存储稀疏矩阵的一类新的对称稀疏行格式
类对象----------Objects from the Class----------
Objects can be created by calls of the form new("matrix.ssr", ...).
可以创建对象通过调用的形式new("matrix.ssr", ...)。
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 row order. Thus, if i<j, all elements of row i precede elements from row j. The order of elements
ra:对象类numeric,NNZ元素包含非零元素的下三角部分A,行顺序存储在一个真正的数组。因此,如果I <J,行,我行j的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 column
ja:类的对象integer,NNZ元素的整数数组包含列
ia: Object of class integer, an integer array of n+1 elements containing pointers to the beginning of each row in the arrays "ra" and "ja". Thus "ia[i]" indicates the position in the arrays "ra" and "ja" where the ith row begins. The last, (n+1)st, element of "ia" indicates where the n+1 row would start, if it existed.
ia:类integer,一个整数数组中的n +1个元素阵列的Ra“和”JA“中的每一行的开头包含指针的对象。因此,IA [i]的表示的阵列岭和ja的,其中开始的第i行中的位置。最后,(N +1)日,元素的“IA”表示,其中N +1行开始,如果它存在。
dimension: Object of class integer, dimension of the matrix
dimension:对象类integer,维数的矩阵
