Hi, I need to do the following and I hope you can help me.
given a vector of (for example):
a=[3 9 32 6 5 6 7 1 2 10];
choose the first 5 positions upside down and 5 the next ones too but I must assign the value of position 6 to the next row of the matrix in position one, after that I need to see the resulting matrix, sorry for the bad explanation, to next I added an example of what I want to obtain
M= [5 6 32 9 3; 6 5 6 32 9; 7 6 5 6 32; 1 7 6 5 6 ... etc]
Thanks for reading and of course taking your time, I am not good enough in matlab but i I hope to impove my skills :D

>> a = [3,9,32,6,5,6,7,1,2,10];
>> toeplitz(a(5:end),a(5:-1:1))
ans =
5 6 32 9 3
6 5 6 32 9
7 6 5 6 32
1 7 6 5 6
2 1 7 6 5
10 2 1 7 6
