2])会画出深灰色线条。涉及颜色映射的场景，需自订义colormap，用colormap(custom_cmap)应用该映射，此时颜色索引值越大对应颜色越深创建从浅到深的颜色梯度矩阵，比如用linspace函数生成100行灰度值矩阵：custom_cmap= [linspace(0.9,0.1,100)’ linspace(0.9,0.1,100)’ linspace(0.9,0.1,100)’]。

可以使用MATLAB中的函数imwrite()来指定某位置的像素为彩色。该函数可以将图像写入到指定的文件中,并可以指定图像的颜色模式,如RGB(红色、绿色、蓝色)、CMYK(青色、品红、黄色、黑色)等。例如: imwrite(I, 'myimage.png', 'Color', 'RGB'); 其中,I为要写入的图像,myimage.png为要写入的文件名,Color为颜色...
