MATLAB中多个一维数组的合并

1、一维数组直接合并

       题目：

           数组work1[x1,x2——,xn]，work2[y1,y2——,yn]，现在要生成一个数组work3，

       work3中的数据为[x1,x2,x3--xn,y1,y2--yn];

       合并方法：

           直接将两个矩阵合并：

             A = [1,2,3,4];

             B = [-1,-2,-3,-4];

             C = zeros(1,size(B,2)+size(A,2));     %这句可以不要;

             C = [A, B];

    2、一维数组交叉合并：

       题目：

           数组work1[x1,x2——,xn]，work2[y1,y2——,yn]，现在要生成一个数组work3，

       work3中的数据为[x1,y1,x2,y2——,xn,yn];

       合并方法一:

           A = [1,2,3,4];

           B = [-1,-2,-3,-4];

           C = zeros(1,size(B,2)+size(A,2));

           C(1:2:end) = A;

           C(2:2:end) = B

           C =

                1    -1     2    -2     3    -3     4    -4

       解法二：

           A = [1,2,3,4];

           B = [-1,-2,-3,-4];

           C=[A' B']';

           C=reshape(C, 1, length(A)+length(B));

           C =

                1    -1     2    -2     3    -3     4    -4

       解法三：

           对于解法二改进：

           c=reshape([A;B],1,[])；

           这里要注意，只能在v7以上的版本才能使用此法；

       解法四：

           A = [1,2,3,4];

           B = [-1,-2,-3,-4];

           C=kron(A,[1 0])+kron(B,[0 1]);

           C =

                1    -1     2    -2     3    -3     4    -4

      很多技巧，试总结以上的方案：

          -------------------------------------

          A = [1,2,3,4];

          B = [-1,-2,-3,-4];

          ----------------- 1 -----------------

          C = zeros(1,size(B,2)+size(A,2));

          C(1:2:end) = A;

          C(2:2:end) = B;

          C=C(:);

          ------------------2 -----------------

          C=[A' B']';

          C=reshape(C, 1, length(A)+length(B));

          ------------------3-------------------

          c=reshape([A;B],1,[])

          ------------------4-------------------

          C=kron(A,[1 0])+kron(B,[0 1]);
