How to convert a matrix into a vector

I have a matrix and i need to convert it into a vector. Basically i need to remove the dependency of one parameter.Please see the image file i have attached.

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

My objective is to decompose or do some factorization so that the matrix will become a vector with same number of rows with only one column.

How about this to convert the matrix into a column vector

param2 = data2d(:,1); % Convert column 1 of 2-d data matrix into a column vector.

If not, then state your rule(s) for getting each row of your desired output vector.

@praveen — The svd (link) function comes quickly to mind.

From the documentation:

• s = svd(A) returns the singular values of matrix A in descending order.

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
