distance函数在机器学习、图像处理、模式识别等领域中经常被使用。 2. distance函数的语法 distance函数的基本语法如下: d = distance(X,Y) 其中,X和Y是两个n维向量,d是它们之间的距离。 3. distance函数的使用方法 3.1 欧几里德距离 欧几里德距离是最常用的距离度量,它表示两个点之间的直线距离。在Matlab中,...
I have been working on fitting a plane to 3d points and then calculating the perpendicular distance between each point and the plane using Matlab. So far I can find the plane equation in Ax+By+Cz+D=0 form and calculate the distance using (Ax0+By0+Cz0+D)/sqrt(A^2+B^2+C^2). ...
