All the command-line options listed above admit an optional argument specifying
the viewer type and options. For instance, use '-svd_view_mat0 binary:amatrix.bin'
to save the A matrix to a binary file, '-svd_view_values draw' to draw the computed
singular values graphically, or '-svd_error_relative :myerr.m:ascii_matlab' to save
the errors in a file that can be executed in Matlab.
