Sum of a row

Hello,

I have a Matrix 3x30 and I want to have the sum of the first row (element 1 to 30)

Can anyone help me? I just find solutions for sum of a vector or a matrix but I want to have each row seperately.

Thx in advance

sum(yourmatrix, 2)

will give you the sum of each row as 3x1 vector.

sum(yourmatrix(1, :))

will give you the sum of just the first row. (or just take the first element of the previous result)
