{{DISPLAYTITLE:keep_rank.m}} __NOTOC__
Truncates the singular value decomposition at the specified rank and reassembles the matrix.

==Syntax==

A=keep_rank(A,rank)

==Arguments==

A - real or complex matrix, will be
converted to full if a sparse
matrix is received

rank - number of singular values to keep

==Outputs==

A - filtered matrix, returned as full
