基于Matlab的地震数据处理显示和测井数据显示于处理的小程序

function aux=mysuptitle(text,varargin)
% Places text as a title on a group of subplots.
% Returns a handle to the label and a handle to the superaxis.
% Based on function "suplabel" by Ben Barrowes (Matlab File Exchange)

%          title_handle=mysuptitle(text,varargin)
% INPUT
% text     text for the title
% varargin  one or more cell arrays; the first element of each cell array is a
%           keyword, the other elements are parameters. Presently, keywords are:
%     'fontsize'  Size of the title font
%           Default: {'fontsize',16}
%     'yloc'  relative y-location of the title
%           Default: {'yloc',1.00}
% OUTPUT
% title_handle  handle to the title (allows subsequent changes of the title)
% EXAMPLE
%      lfigure
%      subplot(2,2,1);ylabel('ylabel1');title('title1')
%      subplot(2,2,2);ylabel('ylabel2');title('title2')
%      subplot(2,2,3);ylabel('ylabel3');xlabel('xlabel3')
%      subplot(2,2,4);ylabel('ylabel4');xlabel('xlabel4')
%      aux=mysuptitle('super X label',{'yloc',1.05});
%      pause(2)
%      set(aux.title_handle,'FontSize',50,'Color','blue')
