class pylops_mpi.optimization.cls_basic.CG(Op, callbacks=None)

Conjugate gradient

Solve a square system of equations given either an MPILinearOperator or an MPIStackedLinearOperator Op and distributed data y using conjugate gradient iterations.

Parameters:

Oppylops_mpi.MPILinearOperator or pylops_mpi.MPIStackedLinearOperator

Operator to invert of size \([N \times N]\)

Notes

Solve the \(\mathbf{y} = \mathbf{Op}\,\mathbf{x}\) problem using conjugate gradient iterations.
