You did not state the result you want. One obvious option is to use the reshape (link) function.

Hello Star Strider this is exactly the concept i was looking for. I tried this and it gave me a single column vector but with reduced number of rows.If you look at the image i posted in the question the output will have equal number of rows when compared to the input.Please let me know if a modified SVD or any other similar concept is capable of doing this. Thank you very much for the answer.

If the mathematics are not important and any procedure will do, the easiest approach would likely be something like:
Result = mean(A,2,'omitnan')
where ‘A’ is your matrix.

%%%% Converting Matix to vector
A = [1 2 3; 4 5 6; 7 8 9] % Example matrix
reshape(A,[],1) % convert matrix to column vector
reshape(A,1,[]) % convert matrix to row vector
