Unformatted text preview: Computer Question 1: Plot Write Matlab code that displays the following four graphs next to each other (in one figure) as seen below. Let x contain 100 evenly spaced points, running from 1 to 10. Title and label both the x and y axes of your graph. a) y = log(x) b) y = e x c) y = e x+5 d) y = cos 2 (x) x = linspace(0,10,100); subplot(2,2,1); plot(x, log(x)); title(log x); xlabel(x); ylabel(y); subplot(2,2,2); plot(x, exp(x)); title(e to the x); xlabel(x); ylabel(y); subplot(2,2,3); plot(x, exp(x+5)); title(e to the x+5); xlabel(x); ylabel(y); subplot(2,2,4); plot(x, cos(x).^2); title(cosine squared); xlabel(x); ylabel(y); -4 if they have minor syntax errors (they had the computer to check answers) -6 if they are missing titles, xlabels, and/or ylabels, or cant dot multiply/exponentiate -8 if they at least successfully use 2 of the following: subplot, plot, and linspace -10 if they at least successfully use 1 of the following: subplot, plot, and linspace -12 if they seem to kind of understand how to plot things...
