  15. Simple guide(command window) • >> 1+3/2 %simple guide ans = 2.5000 • >> 1+3/2+2*2; • >> x=3*3 x = 9

  16. Simple guide(matrix&vector) >> s = [1 3 5 2]; % The number is separated by “space”. >> t = 2*s+1 t = 3 7 11 5 ************************************************************ >> A = [1 2 3 4; 5 6 7 8; 9 10 11 12]; % build a3×4 matrixA >> A % Show the content of A A = 1 2 3 4 5 6 7 8 9 10 11 12

  17. Simple guide(matrix&vector) >> AT=A‘ % AT is transporse of A AT = 1 5 9 2 6 10 3 7 11 4 8 12

  23. Condition • If

  24. Solve(linear) >>syms x; >>solve(x^4 + 1 == 2*x^2 - 1)ans = (1 + i)^(1/2) (1 - i)^(1/2) -(1 + i)^(1/2) -(1 - i)^(1/2)

  25. Plot clear all; t=0:0.01:3; h=0.01; i=1; while t(i)<3 y(i)=t(i)^2-2*t(i)+1; i=i+1; end y(i)=t(i)^2-2*t(i)+1; plot(t,y); hold on; % Hold the plot plot(t,cos(t),'red');

  26. Plot(axis) • axis([xmin, xmax, ymin, ymax]); • For example:>>axis([-2,2 ,-2,2]);

  27. Plot(label) clear all; t=0:0.01:3; h=0.01; i=1; while t(i)<3 y(i)=t(i)^2-2*t(i)+1; i=i+1; end y(i)=t(i)^2-2*t(i)+1; plot(t,y); hold on; % Hold the plot plot(t,cos(t),'red'); xlabel('X'); ylabel('Y');

  28. Animation t=0:0.01:10; x=0:0.01:5; h=0.01; j=1; while t(j)<10 i=1; while x(i)<5 y(i)=x(i)*sin(5*x(i)-5*t(j)); i=i+1; end y(i)=x(i)*sin(5*x(i)-5*t(j)); plot(x,y); axis([0,5,-5,5]); M(j)=getframe j=j+1; end

  29. Animation i=1; while x(i)<5 y(i)=x(i)*sin(5*x(i)-5*t(j)); i=i+1; end y(i)=x(i)*sin(5*x(i)-5*t(j)); plot(x,y); M(:,length(t))=getframe; movie(M,3) %play the animation movie2avi(M,'exampleformovie.avi','compression','None');
