Hello
P is a matrix of 100 106 and I am trying to add 20 constant values (say 0.25) above each row and 20 constant values (say 0.21) below each rows to make P as 140 106. How I can change following code? instead of taking first value of each column (P(1,:)), how I can replace with a constant value?
A_pad = zeros(140,106);
A_pad(1:20,:) = ones(20,1)*P(1,:);
A_pad(21:120,:) = P;
A_pad(121:140,:) = ones(20,1)*P(end,:);

A = magic(4)
B = [repmat(-999, 2, width(A));
A;
repmat(Inf, 3, width(A))]
This pads 2 rows containing the constant -999 above the matrix A and 3 rows containing the constant Inf below.
