QuadPotentialDiag
(v, dtype=None)¶ Quad potential using a diagonal covariance matrix.

__init__
(v, dtype=None)¶ Use a vector to represent a diagonal matrix for a covariance matrix.
Parameters: - v : vector, 0 <= ndim <= 1
Diagonal of covariance matrix for the potential vector
Methods
__init__
(v[, dtype])Use a vector to represent a diagonal matrix for a covariance matrix. energy
(x[, velocity])Compute kinetic energy at a position in parameter space. raise_ok
([vmap])Check if the mass matrix is ok, and raise ValueError if not. random
()Draw random value from QuadPotential. reset
()Reset quadpotential adaptation routine. update
(sample, grad, tune)Inform the potential about a new sample during tuning. velocity
(x[, out])Compute the current velocity at a position in parameter space. velocity_energy
(x, v_out)Compute velocity and return kinetic energy at a position in parameter space. -
