MATLAB: Matlab function send selected variables

bicgstabmatlab function

I am using bicgstab in Matlab. I would like to know how can I call the function without only preconditioner. As per the documentation, below is the order in which variables are to be sent:

bicgstab(A,b,tol,maxit,M1,M2,x0)

I do not want to use M1 and M2. However, I want to send x0. How can I do this?

I don't know what bicgstab() is. The documentation should say whether M1 and M2 are needed. However you didn't share it with us. Usually when some argument is optional, you can pass in [] for it. You might try that and see. If it doesn't work, show us the documentation.

bicgstab(A, b, tol, maxit, [], [], x0)

markers = {'+', 'o', '*', 'x', 's'};
funs = cellfun(@str2fun, funs_cell, 'uniform', 0);
for K = 1 : length(funs)
    plot(x, funs{K}(x), markers{K}, 'DisplayName', funs_cell{K});
    hold on
end

MATLAB: Preconditioning algorithm on GPU for solution of sparse matrices

MATLAB's preconditioning for sparse iterative solvers on the GPU is currently implemented using ILU and sparse triangular solves. If you have a solution more appropriate to your problem then you can use the functional form - this diverts to a different implementation but can be faster and/or converge better depending on your problem.
