You can plot the data in a 2d or 3d view using either a linear or a logarithmic scale. Each element of c specifies the color for one pixel of the image. It started out as a matrix programming language where linear algebra programming was simple. If you do the image after the plot, you wont be able to see the plot because it will go behind the image. Display a grayscale, rgb truecolor, indexed or binary image using imshow. Matlab is a programming language developed by mathworks.
When it opens, sliceviewer displays the middle image in the stack in the direction. The row and column indices of the elements determine the centers of the corresponding pixels.
