UFget and UFgui interfaces to the UF Sparse Matrix Collection

UFget and UFgui provide easy access to the collection and a simple but powerful search interface, both inside and outside of MATLAB.

UFget for MATLAB

UFget downloads a matrix, caches it locally, and loads it directly into your MATLAB workspace. No need to use a browser to get a matrix. You can even use the built-in index to search for matrices that fit your criteria ... all inside MATLAB. For example, to download all symmetric matrices into MATLAB, in increasing size as measured by nnz(A):

    index = UFget ;           % get index of the UF Sparse Matrix Collection 
    ids = find (index.numerical_symmetry == 1) ;
    [ignore, i] = sort (index.nnz (ids)) ;
    ids = ids (i) ;
    for id = ids
	Prob = UFget (id)     % Prob is a struct (matrix, name, meta-data, ...)
	A = Prob.A ;          % A is a symmetric sparse matrix
    end

The collection also appears as a Public Data Set hosted by Amazon Web Services, aws.amazon.com.
Wolfram Research is planning to mirror the entire collection to enable access via Mathematica.

UFgui Java interface

The UFget package includes a Java program (UFgui) for downloading the matrices in any format on any platform. Below is a screenshot with the default UFgui icon. Java 1.6.0 (JDK SE 6) or later is required.
