icgstab 2bicgstab Purpose BiConjugate Gradients Stabilized method Syntax x = bicgstab(A,b) bicgstab(A,b,tol) bicgstab(A,b,tol,maxit) bicgstab(A,b,tol,maxit,M) bicgstab(A,b,tol,maxit,M1,M2) bicgstab(A,b,tol,maxit,M1,M2,x0) bicgstab(afun,b,tol,maxit,m1fun,m2fun,x0,p1,p2,...) [x,flag] = bicgstab(A,b,...) [x,flag,relres] = bicgstab(A,b,...) [x,flag,relres,iter] = bicgstab(A,b,...) [x,flag,relres,iter,resvec] = bicgstab(A,b,...) Description x = bicgstab(A,b) attempts to solve the system of linear equations A*x=b for x. The n-by-n coefficient matrix A must be square and the column vector b must have length n. A can be a function afun such that afun(x) returns A*x. 2-154 If bicgstab converges, a message to that effect is displayed. If bicgstab fails to converge after the maximum number of iterations or halts for any reason, a warning message is printed displaying the relative residual norm(b-A*x)/ norm(b) and the iteration number at which the method stopped or failed. bicgstab(A,b,tol) specifies the tolerance of the method. If tol is [], then bicgstab uses the default, 1e-6. bicgstab(A,b,tol,maxit) specifies the maximum number of iterations. If maxit is [], then bicgstab uses the default, min(n,20). bicgstab(A,b,tol,maxit,M) and bicgstab(A,b,tol,maxit,M1,M2) use preconditioner M or M = M1*M2 and effectively solve the system inv(M)*A*x = inv(M)*b for x. If M is [] then bicgstab applies no preconditioner. M can be a function that returns M\x. bicgstab(A,b,tol,maxit,M1,M2,x0) specifies the initial guess. If x0 is [], then bicgstab uses the default, an all zero vector.
Example Example 1. bicgstab bicgstab(afun,b,tol,maxit,m1fun,m2fun,x0,p1,p2,...) passes parameters p1,p2,... to functions afun(x,p1,p2,...), m1fun(x,p1,p2,...), and m2fun(x,p1,p2,...). [x,flag] = bicgstab(A,b,...) also returns a convergence flag. Flag Convergence 0 bicgstab converged to the desired tolerance tol within maxit iterations. 1 bicgstab iterated maxit times but did not converge. 2 Preconditioner M was ill-conditioned. 3 bicgstab stagnated. (Two consecutive iterates were the same.) 4 One of the scalar quantities calculated during bicgstab became too small or too large to continue computing. Whenever flag is not 0, the solution x returned is that with minimal norm residual computed over all the iterations. No messages are displayed if the flag output is specified. [x,flag,relres] = bicgstab(A,b,...) also returns the relative residual norm(b-A*x)/norm(b). If flag is 0, relres
