ivan@128 2 %% Example test of solvers on Sparco audio source separation problems
idamnjanovic@1 3 %
idamnjanovic@1 4 % The main purpose of this example is to show how to use SMALL structure
idamnjanovic@1 5 % to solve SPARCO audio source3 separation problems (401-402) and to
idamnjanovic@1 6 % compare results from different solvers.
idamnjanovic@1 7 % To generate SMALL.Problem part of structure you can use generateProblem
idamnjanovic@1 8 % function from Sparco toolbox giving the problem number and any
idamnjanovic@1 9 % additional parameters you might want to change. Alternatively, you can
idamnjanovic@1 10 % might want to consult sparco documentation to write a problem by
idamnjanovic@1 11 % yourself. There are four fields the must be specified in SMALL.Problem
idamnjanovic@1 12 % - A, b, sizeA and reconstruct.
idamnjanovic@1 13 %
idamnjanovic@1 14 % To generate SMALL.solver part of the structure you must specify three
idamnjanovic@1 15 % fields:
idamnjanovic@1 16 %
idamnjanovic@1 17 % SMALL.solver.toolbox - string with toolbox name is needed because
idamnjanovic@1 18 % different toolboxes are calling solver
idamnjanovic@1 19 % functions in different ways.
idamnjanovic@1 20 % SMALL.solver.name - its string representing solver name (e.g.
idamnjanovic@1 21 % SolveBP)
idamnjanovic@1 22 % SMALL.solver.param - string that contains optional parameters for
idamnjanovic@1 23 % particular solver (all parameters you want to
idamnjanovic@1 24 % specify except A, b and size of solution)
idamnjanovic@1 25 %
idamnjanovic@1 26 % Every call to SMALL_solve function will generate following output:
idamnjanovic@1 27 %
idamnjanovic@1 28 % SMALL.solver.solution - contains solution vector x
idamnjanovic@1 29 % SMALL.solver.reconstructed - vector containing signal reconstructed
idamnjanovic@1 30 % from the solution
idamnjanovic@1 31 % SMALL.solver.time - time that solver spent to find the solution
idamnjanovic@1 32 %
idamnjanovic@1 33 % SMALL_plot function plots the SMALL.solver.solution and reconstructed
idamnjanovic@1 34 % sources against original audio sources.
idamnjanovic@1 35 % SMALL_playAudio function plays audio sources of original and
idamnjanovic@1 36 % reconstructed signal as well as mixed signal.
