Unformatted text preview: Matlab Practice 1. Please use ‘help’ command to learn the following useful matlab build-in functions by yourself. abs, min, max, sum, ones, zeros, exp, log, sqrt, disp, input, load, length, size, trapz, spline, ode45, odeset,reshape, image, plotyy, linspace, subplot, rand, floor accelerate key: stop ctrl + C comment ctrl + R uncomment ctrl + T smart indent ctrl + I save and run F5 2. 2-D plotting clear % plot x = 0:pi/100:2*pi; y1 = sin(6*x); y2 = 2*cos(x); plot(x,y1,x,y2); Q : The code above generates a simple plot, can you add or change a few lines of code to make the plot like the two below? % add your code to make your plot like the % one on your right. 1 2 3 4 5 6 7-2.5-2-1.5-1-0.5 0.5 1 1.5 2 2.5 Plot of f(x)= sin(6*x) and 2*cos(x) x y sin(6*x) 2*cos(x) 1 2 3 4 5 6 7-2-1.5-1-0.5 0.5 1 1.5 2 % make changes to the original code to make % the plot like the one on your right 3. function m-file x = aV + b , y = bV – a, where a=2, b=3. Try to construct a function m-file to make 2D plot for x x = aV + b , y = bV – a, where a=2, b=3....
