The document discusses visualizing data in Matlab. It describes how the plot function can be used to create graphs with different parameters. It also explains how to create animations by saving multiple frames from figures using getframe and playing them back with movie. An example is provided to generate an animation by plotting the FFT of an identity matrix over increasing sizes and saving each frame.

2. Plots Plot is a MATLAB function which allows users to plot graphs of various kinds and with several possible parameters.

3. Plots >>plot((rand(5,5)*100))

4. Plots >> plot(sin(1:0.1:20))

5. Plots >> plot(sin(1:0.1:20)); grid on;

8. Animation Ways to Animate Plots You can create animated sequences with MATLAB graphics by saving a number of different pictures and playing them back as a movie. >>F = getframe(h) gets a frame from the figure or axes identified by handle h. >> movie(M) plays the movie in matrix M once, using the current axes as the default target.

9. Animation >> for k = 1:16 plot(fft(eye(k+16))) axis equal M(k) = getframe; end >> movie(M);
