12.14) Image Visualization

Now let's take a close look at visualizing matrix data (image data).

• Matlab has a number of functions to provide reading, viewing and the saving of image data.
• These data could be in the form of geographic plots of climatological data, model outputs or observations. We could also have a digital image from an optical microscope or SEM.
• Let's look at some of the Matlab tools:
