Solving an Equation Using a Formula with an Increasing Level of Values

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

Answer 1

[Walter Roberson]

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

ans = 6×4

I don't understand why we divide by 2?

[Walter Roberson]

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