Hi, I have this U shape which is in this code. I was wondering how I could rotate it using 2-D rotation matrix.
theta = pi/2;rotation_matrix = [cos(theta), -sin(theta); sin(theta), cos(theta)];obstacle_matrix = [z1, z2];obstacle_shape = obstacle_matrix * rotation_matrix;plot(obstacle_shape)
here is my other file.
% obstacle definition
function [z1 z2] = toric_obstacle(enl_fac)x0 = -1.2*enl_fac;y0 = -1*enl_fac;x1 = -0.6/enl_fac;y1 = -0.5/enl_fac;x2 = 0.6/enl_fac;x3 = 1.2*enl_fac;y3 = 0.8*enl_fac;delta = 0.01;z1 = zeros(1000,1);z2 = zeros(1000,1);%line 1
i = 0;for x = x0:delta:x3 i = i + 1; z1(i) = x; z2(i) = y0;end%line 2
i = i - 1;for y = y0:delta:y3 i = i + 1; z1(i) = x3; z2(i) = y;end%line 3
i = i - 1;for x = x3:-delta:x2 i = i + 1; z1(i) = x; z2(i) = y3;end%line 4
i = i - 1;for y = y3:-delta:y1 i = i + 1; z1(i) = x2; z2(i) = y;end%line 5
i = i - 1;for x = x2:-delta:x1 i = i + 1; z1(i) = x; z2(i) = y1;end%line 6
i = i - 1;for y = y1:delta:y3 i = i + 1; z1(i) = x1; z2(i) = y;end%line 7
i = i - 1;for x = x1:-delta:x0 i = i + 1; z1(i) = x; z2(i) = y3;end%line 8
i = i - 1;for y = y3:-delta:y0 i = i + 1; z1(i) = x0; z2(i) = y;endi = i - 1;z1 = z1(1:i);z2 = z2(1:i);
