shape_check	Check that the given Gaussian representation is consistent with the given modes.

reshape_params

mrmustard.lab.utils.reshape_params(n_modes, **kwargs)

A utility function to turn the input parameters of states and gates into 1-dimensional tensors of length n_modes.

Parameters:

• n_modes (int) – The number of modes.

• **kwargs – The parameters to reshape.

Raises:

• ValueError – If a parameter has a length which is neither equal to 1

• nor n_modes. –

Return type:

Generator

shape_check

mrmustard.lab.utils.shape_check(mat, vec, dim, name)

Check that the given Gaussian representation is consistent with the given modes.

Parameters:

• mat – matrix (e.g. A or cov, etc.)

• vec – vector (e.g. b or means, etc.)

• dim (int) – The required dimension of the representation

• name (str) – The name of the representation for error messages
