I needed matlab code for cumulative sum of column vector

I needed matlab code for cumulative sum of column vector

Answer 1

[Azzi Abdelmalek]

yourarray=[1 2 3 4 5]
out=cumsum(yourarray)

[maha ismail]

I need matlab such that for I=1 :4 s=cumsum (q(:,I)) End

I know cumsum deal with row vector not column vector

[Azzi Abdelmalek]

yourarray=[1 ;2; 3; 4; 5] % a column vector
out=cumsum(yourarray)

[maha ismail]

I ll try it

[maha ismail]

it doesn't work as I need I need to produce I column vector also not a scalar because I need cumulative sum for more colmun vector such that each row element of new column vector coming from current and previous element row of vectors

[Azzi Abdelmalek]

Maybe you need this

yourarray=[1 2 3;4 5 6]
out=cumsum(yourarray,1)

%or

yourarray=[1 2 3;4 5 6]
out=cumsum(yourarray,2)
