SMaSTo (Sparse MAtrix Storage TOols) is a set of command-line utilities to manipulate matrix files in the SMS format (used for instance by the LinBox linear algebra library).

Tools currently included in SMaSTo include:

• sms-adjoin: stack matrices or adjoin them side-by-side
• sms-info: print matrix dimensions, number of nonzeroes, and fill-in percentage.
• sms-norm: compute matrix norm (choose between L¹, L², or L^\infty metric).
• sms-random: generate a random sparse matrix of given density.
• sms-reord: Permute matrix rows to speedup Gaussian Elimination.
• sms-rescale: Copy matrix, multiplying all entries by a scale factor.
• sms-shrink: Remove rows and columns consisting entirely of zeroes.
• sms-transpose: Transpose matrix.

For more details, installation and usage instructions, read the manual.
