matrix.ssc-class: Class "matrix.ssc"
Description
A new class for sparse matrices stored in symmetric sparse column formatObjects from the Class
Objects can be created by calls of the form new("matrix.ssc", ...).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 ja:- Object of class
integer, an integer array of nnz elements containing the row
indices of the elements stored in `ra'. 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.
dimension:- Object of class
integer, dimension of the matrix
