## Matlab Using FFT

This demonstration uses the FFT function to analyze the variations in sunspot activity over the last 300 years. Sunspot activity is cyclical, reaching a maximum about every 11 years. Let’s confirm that. Here is...

## Displaying Graphics Images

Image Types and Display Methods To display a graphics file image, use either image or imagesc. For example, assuming RGB is an image, figure(‘Position’,[100 100 size(RGB,2) size(RGB,1)]); image(RGB); set(gca,’Position’,[0 0 1 1]) [warning]This image...
