fullup: Convert Symmetric Sparse Matrix to Full Matrix
Description
fullup converts a symmetric sparse matrix sA, stored as an upper triangular matrix, to a full matrix A.
Usage
fullup(sA)
Value
A Full symmetric matrix.
Arguments
sA
Matrix (sparseMatrix). Symmetric upper triangular matrix to be converted.
Details
This function can be used for transforming matrices that have been stored in a memory-efficient format (i.e., the upper triangle portion of a symmetric matrix) to their full format. The conversion is done either by directly transforming the sparse matrix or by leveraging the full function.
