Attributes

`exportFilters`	list() -> new empty list
`ui_file`	str(object=’’) -> str

Methods

`export_to`(filename)
`showEvent`(self, QShowEvent)

madgui.online.diagnostic.solve_emit_sys(Ms, XCs)[source]¶

Solve for S the linear system of equations:

(M S Mᵀ)ₓₓ = C

For some M, x and C.

M can be coupled, but S is assumed to be block diagonal, i.e. decoupled:

S = (X 0 0
0 Y 0 0 0 T)

Returns S as numpy array.

madgui.online.diagnostic.twiss_from_sigma(sigma)[source]¶: Compute 1D twiss parameters from 2x2 sigma matrix.
