Rotate a 2D function regarding Z-axis (Matlab script)
Código de Matlab: % Rotate a 2D function with respect z-axis x = -10:0.01:10; y = 3*cos(4*x); v = [x(:) y(:)]; % theta is in radians (2*pi is equivalent to 360 degrees) for theta = 0:0.01:2*pi % Matrix rotation wit respect z-axis order: 2 x 2 R = [cos(theta) -sin(theta); sin(theta) cos(theta)]; % Multiply the matrix v x R (to rotate all the 2D space) ... v is N x 2 order and R is 2 x 2 order then ... vr is of N x 2 order vr = v*R; x = vr(:,1); y = vr(:,2); plot(x,y,'Linewidth',4); axis([-15 15 -15 15]); pause(0.01); end Video: https://youtu.be/Et3fGNrPprM
