Class

NumCosmoMathReparamLinear

Description [src]

final class NumCosmoMath.ReparamLinear : NumCosmoMath.Reparam
{
  /* No available fields */
}

Linear reparametrization object.

Object implementing a linear reparametrization of the model’s parameters. It uses as imput a matrix $M$ (NcmReparamLinear:matrix) and a vector $v$ (NcmReparamLinear:vector), such that the new parameters $\vec{w}$ are given by $$\vec{w} = M\cdot\vec{y} + \vec{v},$$ where $\vec{y}$ represents the original model’s parameters.

Ancestors

Constructors

ncm_reparam_linear_new

Creates a new reparametrization using the parameters transformation matrix T and the shift vector v, i.e., the new parameters vector $\vec{p}_n$ is given by $\vec{p}_n = T\cdot{}\vec{p} + \vec{v}$, where $p$ are the old parameters vector.

Instance methods

ncm_reparam_linear_set_compat_type

Sets the object’s type compatible with this reparametrization.

Methods inherited from NcmReparam (13)

ncm_reparam_free

Decreases the reference count of reparam by one. If the reference count reaches zero, the NcmReparam is freed.

ncm_reparam_get_compat_type

Gets the compatible GType for this reparametrization.

ncm_reparam_get_length

Gets the number of parameters.

ncm_reparam_get_param_desc

Gets the i-th parameter description.

ncm_reparam_index_from_name

Looks for a parameter named param_name and returns TRUE if found. If found puts at i its index.

ncm_reparam_new2old

Using the values set in the new parametrization update the values of the original parametrization.

ncm_reparam_old2new

Using the values set in the original parametrization update the values of the new parametrization.

ncm_reparam_peek_param_desc

Peeks the i-th parameter description.

ncm_reparam_peek_params

Gets the NcmVector containing the new parameters. This vector is owned by the NcmReparam and should not be freed. This method is used by NcmModel and subclasses to get the new parameters and should not be used by the user. The pointer returned by this method is guaranteed to be valid until the destruction of the NcmReparam.

Properties

NumCosmoMath.ReparamLinear:matrix

The matrix $M$.

NumCosmoMath.ReparamLinear:vector

The vector $\vec{v}$.

Signals

Signals inherited from GObject (1)

GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
