matlab如何读取一维数组中的指定某些条件数据，并赋值给不同矩阵

p=[0,0,105,201,0,0,0,211,101,0,0,0,0,205,150,189,0,0,0,0];
假设给定的数为上述所示，其中，0的多少以及大于0 的数的个数都没有规律，现在是想把连续的大于0的数提取出来放到不同的矩阵中，比如
a1[105,201];
a2[211.101];
a3[205,105,189];

Answer 1

p=[0,0,105,201,0,0,0,211,101,0,0,0,0,205,150,189,0,0,0,0];

s=size(p,2);

for i=1:s-3

    if p(i)==0&&p(i+1)>0&&p(i+2)>0

        for j=i+1:s

            if p(j)<=0

                m=j-1;

                break

            end

        end

        p(i+1:m)

    end

end

运行结果：

给你个例子：
>> a=rand(10,10);
>> a(3:9,2:8)=10
a =
