基于matlab的反演程序,用于地球物理勘探中射线追踪及偏移成像程序.

% CREWES display tools
%
% Seismic plotting
%  DBSPEC ... compute and plot the Fourier amplitude spectrum of a trace using a decibel scale
%  PLOTIMAGE ... Image display utility for seismic matrices (fast and full featured)
%  PLOTSEIS ... Plot a seismic matrix (trace gather) using WTVA format
%  WTVA ... plot a seismic trace in wiggle-trace variable-area format
%
% Utilities
%  BIGFIG ... enlarges a figure to an optimal size for a slide
%  BIGFONT ... increases (or decreases) fontsize in a figure
%  BOLDLINES ... changes the thickness of lines and the size of markers
%  CLEARPICKS ... clear (delete) the picks in a figure
%  DBSPEC ... plots a Fourier amplitude spectrum using a decibel scale
%  FLIPX ... script to flip the direction of the x (horizontal) axis
%  FLIPY ... script to flip the direction of the y (vertical) axis
%  GREYFIG ... changes the current figure's background to grey
%  HIDEUI ... hide (or restore) user interface controls
%  PLOTIMAGE ... Image display utility for seismic matrices
