I want to multiply for 2.5 the all the rows (2 in total) but not the 1 column, how should I do?
Like this I litterally get rid of the column 1 after multiplying for 2.5.
scores = score(1:2,2:21).*(2.5)
Thank you for you help
Best

You are close to the answer, but you need to keep the first column
% your matrix with data
A = rand(2,21);
% multiply all but the first column
B = [A(:,1) A(:,2:end)*2.5];
