MH2DGRAV

MH2DGRAV is continuous two-dimension inversion of Gravity data based on Talwani formulation using very fast simulated annealing (VFSA) in MATLAB.

These were scripts that were used to implement our paper: W. Srigutomo, M. Heriyanto, and M. Hilmi Aufa. Gravity Inversion of Talwani Model using Very Fast Simulated Annealing. Journal of Mathematical and Fundamental Sciences, Vol. 51, No. 2, 2019, 177-190. doi: 10.5614/j.math.fund.sci.2019.51.2.7 (PDF). I presented this paper on International Conference on Mathematics and Natural Sciences 2016. Nov 2, 2016 (SLIDE). These scripts contain two main scripts: forward and VFSA inversion: horizontal model. Tutorial video on YouTube: VFSA.

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/mh2dgrav.

Forward result

• Kernel Matrix for forward modeling

• Data with 10% noise by horizontal model

• Data with 10% noise by vertical model

VFSA Inversion result

• Data with 10% noise by horizontal model

• Data with 10% noise by vertical model

Usage
