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

在 MATLAB Online 中打开

>> 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
