There is a matrix, for each section you need to add a value, how can this be done?
v = [1 2 3 4] ;
iwant = repmat(v,6,1)
% formula v+0.5*cos(7)/pi % presented without multiplication by cosine and division by pi
iwant = 6×4
1.5 2.5 3.5 4.5
2 3 4 5
2.5 3.5 4.5 5.5
3 4 5 6
3.5 4.5 5.5 6.5
4 5 6 7

v = [1 2 3 4] ;
iwant = repmat(v,6,1);
iwant + (1:6).'/2
ans = 6×4

We want to add 1/2 to the first row, 2/2 to the second row, 3/2 to the third row...
