How to produce a matrix which size is 7*7 and contains all possible single locations of a certain value and the rest of the column's values are 1. For example : The value is 0.4 and I want to produce seven columns of different single locations of 0.4 and the other values are 1 such as: [0.4 1 1 1 1 1 1; 1 0.4 1 1 1 1 1; 1 1 0.4 1 1 1 1; 1 1 1 0.4 1 1 1; 1 1 1 1 0.4 1 1; 1 1 1 1 1 0.4 1; 1 1 1 1 1 1 0.4]

M = ones(7);
C = M;
C(logical(eye(7))) = 0.4
%or
M = ones(7);
C = M;
C(1:size(C,1)+1:end) = 0.4
%or
M = ones(7);
C = M - 0.6 * eye(size(M))
