Minor changes.

- matfaust.quickstart.quick_start() returns the quick_start matrix, useful for the quick start guide.
- Several complements in quick start documentation.

Thanks to Romain Lebarbenchon for its feedback.

 ### 3.1 Testing the Matlab Wrapper
 
 To test whether the FAµST Matlab wrapper auto-setup succeeded at install stage, you can open a terminal and type:
 
-	matlab -nodisplay -nojvm -r "import matfaust.FaustFactory;F = FaustFactory.rand(1, 10, .5, 'dense', 'complex');disp(F);exit"
+	matlab -nodisplay -nojvm -r "import matfaust.FaustFactory;F = FaustFactory.rand(1, 10, .5, 'dense', 'complex'); F"
 
 Note: if Matlab is not set in your PATH environment variable you need to replace `matlab' with its full path
 	(e.g. on macOS /Applications/Matlab/MATLAB_R2018b.app/bin/matlab)
 
 It works only if you see an output similar to:
 
-	Faust size 10x10, density 0.57, nnz_sum 57, 1 factor(s):
-	- FACTOR 0 (complex) DENSE, size 10x10, density 0.57, nnz 57
+	Faust size 10x10, density 0.50, nnz_sum 50, 1 factor(s):
+	- FACTOR 0 (complex) DENSE, size 10x10, density 0.5, nnz 50
 	>> % other values are possible for density, etc. because of the random generation
 
 Otherwise it didn't work. So here is how to setup the wrapper manually.
