repeated row within a matrix

Hello,

Please help me with the following:

Consider an unknown number of vectors x.

This number is generated randomly.

All the vectors are 1x10.

Also, we have a specific vector m that is also 1x10.

How the matrix A is formed, where the vector m is repeated every second row?

For example, the rows of A are:

1st row: 1st vector

2nd row: vector m

3rd row: 2nd vector

4th row: vector m .

.

.

(x-1)th row: xth vector

xth row: vector m

Thank you very much.

Best,

Natasha

 n=randi(100,1)
x=rand(n,10)' % your n vector;
m=ones(1,10) % your special vector
y=repmat(m,n,1)'
res=[x;y];
result=reshape(res(:),10,2*n)'
