MATLAB: How to remove successive repeated numbers (column wise) from a matrix

Question

For example If I have a matrix like this

A = [11 35 57 45 94;
     26 45 69 45 86;
     58 45 39 96 35;
     87 59 64 56 45]

The output should be a column vector (i have just showed transpose of it)

[11 26 58 87 35 45 59 57 69 39 64 45 96 56 94 86 35 45]'

I have tried to use unique() function but, the output it gives is

[11 26 58 87 35 45 59 57 69 39 64 96 56 94 86]'

Answer 1

Easy peasy

A = [11 35 57 45 94;
     26 45 69 45 86;
     58 45 39 96 35;
     87 59 64 56 45]
B = A(:);

or

B = reshape(A, [], 1)
