用MATLAB绘制一个红灯笼
2024-05-17 19:04:31
PART.1 代码说明
这次留的空着实太小，标志就没咋画齐，大家如果有能力可以自己补全，这次的代码依旧使用了椭圆数据生成函数，不过不同的是这次是靠旋转矩阵构造数据点：
% 椭圆数据点生成函数
function [X,Y]=getEllipse(Mu,XR,YR,theta,pntNum)% Mu | 中心点% XR,YR | 旋转前X,Y半轴长度% theta | 旋转角度% pntNum | 生成数据点个数tList=linspace(0,2*pi,pntNum);X=cos(tList).*XR;Y=sin(tList).*YR;rotateMat=[cos(theta),-sin(theta);sin(theta),cos(theta)];XY=rotateMat*[X;Y]+Mu(:);X=XY(1,:);Y=XY(2,:);
end
这次代码还用到各种旋转过后的正弦函数，因此最后的局部函数还包含一个旋转数据的局部函数。
% 数据旋转角度
function [X,Y]=rotateData(X,Y,theta)rotateMat=[cos(theta),-sin(theta);sin(theta),cos(theta)];XY=rotateMat*[X;Y];X=XY(1,:);Y=XY(2,:);
end
