gstools.tools.tpl_gau_spec_dens

gstools.tools.tpl_gau_spec_dens(k, dim, len_scale, hurst, len_low=0.0)

Spectral density of the TPLGaussian covariance model.

Parameters:

• k (float) – Radius of the phase: \(k=\left\Vert\mathbf{k}\right\Vert\)

• dim (int) – Dimension of the model.

• len_scale (float) – Length scale of the model.

• hurst (float) – Hurst coefficient of the power law.

• len_low (float, optional) – The lower length scale truncation of the model. Default: 0.0

Returns:

spectral density of the TPLExponential model

Return type:

float
