+    The FAµST toolbox provides algorithms and data structures to decompose a given dense matrix into a product of sparse matrices in order to reduce its computational complexity (both for storage and manipulation).
 
+    FaµST can be used to:
         - speedup / reduce the memory footprint of iterative algorithms commonly used for solving high dimensional linear inverse problems,
-
         - learn dictionaries with an intrinsically efficient implementation,
-
-        - compute (approximate) fast Fourier transforms on graphs."
