debias.m

这是matlab在地球物理数据处理方面的源码

function [newtraces] = debias(traces);

% function debias carries out a simple subtraction of the mean value of
% each trace. This assumes that the debias is due to DC offset shift only
% and subtracts the mean amplitude.

[m,n] = size(traces);
newtraces = traces - ones(m,1)*mean(traces);
