## empymod, revisited

The project around the electromagnetic python modeller `empymod`

grew bigger than anticipated. Here a short summary of what happened since my previous blog entry.

grew bigger than anticipated. Here a short summary of what happened since my previous blog entry.

The electromagnetic python modeller `empymod`

can model electric or magnetic responses due to a three-dimensional electric or magnetic source in a layered-earth model with electric anisotropy, electric permittivity, and magnetic permeability, from very low frequencies to very high frequencies.

A `Python`

wrapper for `FFTLog`

, a logarithmic fast Fourier transform (FFT) in `Fortran`

.

If you are dealing with Magnetotellurics (MT) and are using the 2D inversion routine `MARE2DEM`

, you might be interested in `Edi2Mare`

.

Using `basemap`

(with a modified xkcd-style) to create global and local travel maps.

The dimensions of a pdf produced by matplotlib have not necessarily the dimensions you would expect. Here is a semi-automatic way how to check and adjust the output dimensions.

A little function with which you can fill a grid of regular or irregular spacing either with colours or with a single colour and transparency.

Move the scientific notation in a Matplotlib figure from top to the side; includes some primitive web crawling to get data for the example.

A Matlab GUI example containing most elements to get you up and running if you plan to write a Matlab GUI from scratch.

Plotting a circle with Matplotlib on a figure can be tricky if the figure axes have different dimensions. The customised function `circle`

removes that hurdle.

A `basemap`

example, including accessing some of the wealth of public domain data.

An introduction to the aftershock series of blog posts which are to follow. And a brief run-down of the installation of the corresponding IPython notebook environment.

A quick run-down how I generate these static pages.
