How to reshape the columns of a matrix into one row?

Hello,

please I need help in this:

suppose that we have a (3*4) matrix that have only binary values either 0 or 1, now I need to read this matrix column by column from the top of the column to the bottom. And I concatenate the values of each column with the values of the other columns. So how can I do that?

for example the matrix A= [

0 1 1 1

1 0 1 0

1 0 0 1

]

the ouput of this process hsould be = 011100110101

Regards,

It's not clear what it is you want as an output. If it's a row vector, there's no concatenation involved, you just simply reshape your matrix:

A = [0 1 1 1;
     1 0 1 0;
     1 0 0 1]
 v = reshape(A, 1, [])  %reshape A into one row. Since matlab is column major, this is done column-wise
