+ (description
+ "Low-rank matrix decompositions are fundamental tools and widely used for
+data analysis, dimension reduction, and data compression. Classically, highly
+accurate deterministic matrix algorithms are used for this task. However, the
+emergence of large-scale data has severely challenged our computational
+ability to analyze big data. The concept of randomness has been demonstrated
+as an effective strategy to quickly produce approximate answers to familiar
+problems such as the @dfn{singular value decomposition} (SVD). This package
+provides several randomized matrix algorithms such as the randomized singular
+value decomposition (@code{rsvd}), randomized principal component
+analysis (@code{rpca}), randomized robust principal component
+analysis (@code{rrpca}), randomized interpolative decomposition (@code{rid}),
+and the randomized CUR decomposition (@code{rcur}). In addition several plot
+functions are provided.")
