matrixL: Pathway structure matrix L
Description
A binary matrix of dimension G by K. Entries of 1 indicate
the presence of a probeset-pathway association relationship, whereas
entries of 0 indicate the opposite.Format
The format is:
num [1:50, 1:5] 0 0 0 0 1 0 0 0 0 1 ...Details
matrix L determines the sparsity strcuture of the loading matrix W.
The binary association information can be extracted from many pathway databases,
such as KEGG, BioCarta, etc.
