Biconjugate Gradients Method The biconjugate gradients (BiCG) algorithm was developed to generalize the conjugate gradient (CG) method to nonsymmetric systems. BiCG solves not only the original linear system Ax=b but also the conjugate system ATx∗=b∗. This leads to two sets of conjugate res...
共轭梯度法是一个典型的共轭方向法,它的每一个搜索方向是互相共轭的,而这些搜索方向d仅仅是负梯度方向与上一次迭代的搜索方向的组合,因此,存储量少,计算方便. matlab toolbox The conjugate gradient method aims to solve a system of linear equations, Ax=b, where A is symmetric, without calculation of the...

x = pcg(A,b) attempts to solve the system of linear equations A*x = b for x using the Preconditioned Conjugate Gradients Method. When the attempt is successful, pcg displays a message to confirm convergence. If pcg fails to converge after the maximum number of iterations or halts for any...
The conjugate-gradient method (CGM) is a means for smoothing the decent to an error minimum which incorporates memory of past search directions into the formation of each sequential weight update cycle for a neural network. ...

I use currently mldivide and mrdivide but I'd like to use an iterative method such as conjugate gradient. The only problem is that it requires the right hand side to be column vectors. How can I deal with matrix right hand side? thanks a lot 0 Comments Sign in to...
