MH1DMT

MH1DMT is inversion software using LM (Levenberg-Marquardt), SVD (Singular Value Decomposition), SA (Simulated Annealing), VFSA (Very Fast Simulated Annealing), and MVFSA (Modified Very Fast Simulated Annealing) of one-dimension magnetotellurics (MT) in MATLAB. I created and tested this code using MATLAB R2013a.

These were scripts that were used to implement my thesis in bachelor degree: 1-D Magnetotelluric Data Inversion using Modified Very Fast Simulated Annealing (MVFSA). Physics, Institut Teknologi Bandung (ITB). DOI: 10.13140/RG.2.2.35938.43209. (PDF: full article, cover page). I defensed this thesis on Department of Physics, Institut Teknologi Bandung (ITB). October, 2016 (SLIDE). Tutorial video on YouTube: LM and SVD.

I hope these scripts can help students to enter research on geophysical inversion. Any updates about these scripts can be seen in my blog: https://mheriyanto.wordpress.com/mh1dmt.
