楼主看看用matlab reshape 函数。
B = reshape(A,m,n)
returns the m-by-n matrix B whose elements are taken column-wise from A. An error results if A does not have m*n elements.
这个貌似不是很难。M文件如下：
%将1*30矩阵A转化为3*10矩阵B
A=[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30];
B=ones(3,10);
for i=1:3
for j=1:10
B(i,j)=A(1,(i-1)*10+j);
end
end
B
