WebMar 12, 2024 · 可以使用 MATLAB 中的 surf 函数来画二元函数图像。. 例如,如果要画函数 z = sin (x) + cos (y),可以使用以下代码: [x, y] = meshgrid (-pi:.1:pi); z = sin (x) + cos (y); surf (x, y, z); 这将生成一个三维图像,其中 x 和 y 轴表示函数的输入,z 轴表示函数的输出。. 您可以使用不同 ... WebThe MRI data, D, is stored as a 128-by-128-by-1-by-27 array. The third array dimension is used typically for the image color data. However, since these are indexed images (a colormap, map, is also loaded) there is no information in the third dimension, which you can remove using the squeeze command. The result is a 128-by-128-by-27 array.
