imread和imwrite函数分别用于将图像文件 读入MATLAB工作空间,以及将图像数据和色图数据一起写入一定格式的图像文件。MATLAB支持多种图像文件格式,如.bmp、.jpg、.jpeg、.tif等。 2.image和imagesc函数 这两个函数用于图像显示。为了保证图像的显示效果,一般还应使用colormap函数设置图像色图。 例1-26 有一图像文件flower...
The MATLAB plot gallery provides examples of many ways to display data graphically in MATLAB. You can view and download source code for each plot, and use it in your own MATLAB project.
通常可採用下述方法: 首先,在MATLAB图形窗体中选择【File】菜单中的【Export】选项,将打开图形输出对话框,在该对话框中能够把图形以emf、bmp、jpg、pgm等格式保存。然后,再打开对应的文档,并在该文档中选择【插入】菜单中的【图片】选项插入对应的图片就可以。

MATLAB 通过将数据值映射到颜色图中的颜色来绘制这些对象。Matlab中预设了数十种不同的colormap颜色图,如图:A colormap is a matrix of values that define the colors for graphics objects such as surface, image, and patch objects. MATLAB draws the objects by mapping data values to colors in the ...
