Fix bug #674: typo in documentation example for BiCGSTAB. They are now proper snippet files. 2013-10-16 15:25:39 +02:00			`int n = 10000;`
			`VectorXd x(n), b(n);`
			`SparseMatrix<double> A(n, n);`
			`/* ... fill A and b ... */`
			`BiCGSTAB<SparseMatrix<double> > solver;`
			`solver.compute(A);`
			`x = solver.solve(b);`
			`std::cout << "#iterations: " << solver.iterations() << std::endl;`
