h1. Known Issues

_(For a complete list of issues already reported and their fix status, please refer to the project's issue list - https://code.soundsoftware.ac.uk/issues/)_

h2. SPARCO and fileparts

From version MATLAB R2011a the function @fileparts@ no longer supports four output arguments (see http://www.mathworks.co.uk/help/techdoc/ref/fileparts.html).

The SMALLbox code was updated to reflect this change, but the version of SPARCO currently being downloaded still has that problem. Please refer to this ticket.

To fix this issue, please change the following SPARCO toolbox code:

* Version that *may* cause issues:

<pre>
toolboxes/SPARCO/sparco-1.2/sparcoSetup.m
126: [root, name, ext, versn] = fileparts(w);

toolboxes/SPARCO/sparco-1.2/tools/parseDefaultOpts.m
45:[pathstr, name, ext, versn] = fileparts(mfilename('fullpath'));
</pre>

* Please change to:

<pre>
toolboxes/SPARCO/sparco-1.2/sparcoSetup.m
126: [root, name, ext] = fileparts(w);

toolboxes/SPARCO/sparco-1.2/tools/parseDefaultOpts.m
45:[pathstr, name, ext] = fileparts(mfilename('fullpath'));
</pre>

h2. Tilde (@~@) operator

As of release 2009b MATLAB introduced the tilda (@~@) operator - see http://www.mathworks.co.uk/help/techdoc/rn/br5fo8o-1.html

If you have a previous version of MATLAB you'll need to change this to any other *unused* variable. As of SMALLbox 2.0 this can be found in the following files/lines of code:

<pre>
./DL/two-step DL/dico_update.m:120: [U,~,V] = svd(patch);
./toolboxes/alps/ALPS/infty_ALPS.m:61:[~,N] = size(Phi);
./toolboxes/alps/ALPS/infty_ALPS.m:132: [~, ind_der] = sort(abs(der).*complementary_Xi, 'descend');
./toolboxes/alps/ALPS/infty_ALPS.m:208: [~, ind_z] = sort(abs(z), 'descend');
./toolboxes/alps/ALPS/infty_ALPS.m:235: [v, ~, ~] = cgsolve(cg_A(X_i, X_i), cg_b(X_i), params.cg_tol, params.cg_maxiter, cg_verbose);
./toolboxes/alps/ALPS/thresh.m:3:[~, ind] = sort(abs(x), 'descend');
