size(A, 2)表示取矩阵A的列数。如果A是多维矩阵，则表示的仍然是取每个二维矩阵的列数。举例说明如下：如果A是2维矩阵（行向量或列向量可看为行数或列数为1的矩阵）A=[1, 2, 3; 4, 2, 3];col = size(A, 2); % 计算结果为col=3，因为矩阵A的列数为3% 如果A是多维矩阵（以3维...

s是704*570*3的，X1=[176 150 51]'是3*1的。当K,i有确定值时，如s(1,1,3)就是1*1*3的，实际上就是1*3的，就可与X1'相减了，所以，原程序中可这样改：p1=sum((s(k,i,:)-X1').^2);只增加个转置就行了。而这句话的意思是：先减，再对差的每个元素平方，再求和。

To specify a 1-by-n row vector, set the Size property to [1 n]. To specify an n-by-m matrix, set the Size property to [n m]. To specify an n-dimensional array, set the Size property to [d1 d2 ⋯ dn], where di is the size of the ith dimension. To configure a Statefl...
matlab中size（）的⽤法 size(A)函数是⽤来求矩阵的⼤⼩的,你必须⾸先弄清楚A到底是什么，⼤⼩是多少。⽐如说⼀个A是⼀个3×4的⼆维矩阵：1、size（A） %直接显⽰出A⼤⼩ 输出：ans= 3 4 2、s=size（A）%返回⼀个⾏向量s，s的第⼀个元素是矩阵的⾏数，第⼆个...
