钢厚度的预测是通常的数学统计方法难以拟合的.支持向量机方法能够解决小样本情况下非线性函数拟合的通用性和推广性问题,是求复杂的非线性拟合函数的一种有效的技术.模型及实例表明,该方法对储层厚度的预测是有效的.

2 部分代码

function varargout = XuiGaiMiMa(varargin)
% XUIGAIMIMA MATLAB code for XuiGaiMiMa.fig
% XUIGAIMIMA, by itself, creates a new XUIGAIMIMA or raises the existing
% singleton*.
%
% H = XUIGAIMIMA returns the handle to a new XUIGAIMIMA or the handle to
% the existing singleton*.
%
% XUIGAIMIMA('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in XUIGAIMIMA.M with the given input arguments.
%
% XUIGAIMIMA('Property','Value',...) creates a new XUIGAIMIMA or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before XuiGaiMiMa_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to XuiGaiMiMa_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

% See also: GUIDE, GUIDATA, GUIHANDLES
