この場合、どのようにすれば平面の線形に仰角をつけられるでしょうか？
r2 = 30
r2 = 30
dot = (0:10:350);
[s,t] = meshgrid((dot/180)*pi, (dot/180)*pi)

Z軸を作ってplot3関数で3次元平面にプロットすれば、平面の線形に仰角をつけられます。

dot = (0:10:350) / 180 * pi;
xxr2 = (30 + sin(3*dot)) .* cos(dot);
yyr2 = (30 + sin(3*dot)) .* sin(dot);
plot3(xxr2,yyr2,yyr2);
view(45,45);

dot = (0:10:350) / 180 * pi;
xxr2 = (30 + sin(3*dot)) .* cos(dot);
yyr2 = (30 + sin(3*dot)) .* sin(dot);
figure; view(3); hold on; grid on;
axis([-40 40 -40 40 -40 40]);
f = hgtransform('Matrix', makehgtform('yrotate', deg2rad(20))); %y軸を基準に20°回転
plot(f,xxr2,yyr2);
