Class "matrix.ssr"

A new class for sparse matrices stored in symmetric sparse row format

Keywords
classes
Objects from the Class

Objects can be created by calls of the form new("matrix.ssr", ...).

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 within the rows is immaterial.

ja:

Object of class integer, an integer array of nnz elements containing the column 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 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.

dimension:

Object of class integer, dimension of the matrix
