matlab图像输出设置讲述.docx

核心方法：通过图像设置命令，直接指定图片的大小。具体操作：(1) 完成画图及相关设置(字体大小、线宽、图例大小也是正常尺寸)，(2) 此时WindowStyle is docked，要改为normal，有两种操作：1)在Figure properties——more properties中找到Windowstyle，然后用鼠标改为normal；2)或者直接用命令：set (gcf,windowstyle,normal)(3) 根据排版要求，确定图片的宽高，例如320*320 像素，然后使用命令set (gcf,Position,[500,300,320,320]) set(gcf,Units,centimeters,Position,[100 100 98]);% figure的position中的[left bottom width height] 是指figure的可画图的部分的左下角的坐标以及宽度和高度。(4) 使用copy figure将图片输出到Wordfigure; hold on;set(gca, YTick, [0 : 0.2 : 1]);box off;set(gca, YTickLabel, {matlab1, matlab2, matlab3,...? ? matlab4, matlab5, matlab6})hold onxL=xlim;yL=ylim;plot(xL,[yL(2),yL(2)],k,[xL(2),xL(2)],[yL(1),yL(2)],k)box offaxis([xL yL]) t=linspace(0,8,100);%%% linspace(X1, X2) generates a row vector of 100 linearlyequally spaced points between X1 and X2.linspace(X1, X2, N) generates N points between X1 and X2.a1=axes;%% axes Create axes in arbitrary positions. axes(position, RECT) opens up an axis at the specified locationand returns a handle to it. RECT = [left, bottom, width, height] specifies the location and size of the side of the axis box, relative to the lower-left corner of the Figure window, in normalized units where (0,0) is the lower-left corner and (1.0,1.0) is the upper-right.plot(t,sin(t));xt=get(gca,xtick);set(gca,XTick,[],XColor,w);xL=xlim;p=get(gca,Position);box off;figurea2=axes(Position,p+[0,p(4)/2,0,-p(4)/2]); % 确定坐标位置，p为上述xlim(xL); %定义x轴坐标box off;set(gca,XTick,xt,Color,None,YTick,[]);简单点儿说吧：xtick是刻度（小竖线）；xticklabel 刻度值（竖线下面的数值）。set(gca,xtick,-pi:pi/2:pi)这句的意思是：手动设置x轴刻度，-pi到pi之间，每间隔pi/2，划一小竖线；set(gca,xticklabel,{-pi,-pi/2,0,pi/2,pi})这句的意思是：给刚才划上的小竖线，标个数值。如果你把它改成：set(gca,xticklabel,{a,b,c,d,e})，那么那小竖线下就变成：a,b,c,d,e了。希望对你有用！findobjfindobj：特殊属性的图形对象?语法：1.findobj:findobj返回根对象的句柄和所有子对象（findobj returns handles of the root object and all its descendants without assigning the result to a variable.）2.h = findobj：返回根对象的句柄和所有子对象3.h = findobj(PropertyName,PropertyValue,...)返回所有属性名为‘PropertyName’，属性值为Property
