大地电磁法是20世纪50年代由前苏联提出并经法、美加等过科学家年代由前苏联提出并经法、美加等过科学家过多年努力发展起来的以交变电磁场为源一种物探方法。本文是大地电磁一维正反演的原理和matlab代码。-Magnetotelluric method is put forward by the former Soviet union in the 1950 s and by the method, such as the us and Canada scientist s put forward by the former Soviet union and the method, such as the us and Canada have developed scientists had many years of hard work with alternating electromagnetic field as the source of a geophysical prospecting method. This paper is a d magnetotelluric are inversion principle and matlab code.
