MATLAB——PLOT绘图 格式化绘图: 1.color: b g r c m y k w blue green red cyan magenta yellow black white 2.type of coordinate point . o x + * s d v ^ < > p h point circle x-mark plus star square diamond triangle (down) triangle (up) triangle (left) riangle
动图有gif格式和视频的avi格式. 1.sin(x)动图 clear all h = animatedline;%动画线 axis([0 4*pi -1 1]) box on x = linspace(0,4*pi,200); for k = 1:length(x) y = sin(x(k)); addpoints(h,x(k),y);%将数据添加到动画线中 drawnow%画出动画线 f=getframe(gcf); imind=frame2im(f); [imind,cm] = rgb2i

gcf:获取当前显示图像的句柄: 默认 plot 的 position 是 [232 246 560 420] 0. save >> A = randn(3, 4); >> B = 'hello world'; >> save 'data.mat' A B % 将多个对象保存进 data.mat 文件中 >> save data A B % 两个保存语句是等价的: 1. imwrite.saveas.print I = imread('./name.bmp'
一.图片读取保存 (1)读取 clear all [filename,pathname]=uigetfile({'*.jpg';'*.bmp';'*.gif'},'选择图片'); if isequal(filename,0) disp('Users Selected Canceled'); else str=[pathname filename]; im = imread(str); imshow(im); end (2)保存 clear all x=0:0.01:2*pi; plot(x,si
