In fact, I am going to use this function [F = (a + b) + (a * b)] to fill out the rest of this matrix.  So, the shape of matrix would be in this way:> > a1=b1  a2      a3     a4      a5     a6    a7    a8    a9    a10    a11> b2      b2a2   b2a3   b2a4  b2a5.............................................  > b3      b3a2   .......................................................................> b4      .................................................................................> b5      .................................................................................> b6      .................................................................................> b7      .................................................................................> b8      .................................................................................> b9      .................................................................................> b10    ..................................................................................> b11    .............................................................................b11a11> > Thanks,> Jerry>   If you expand this to 11x11 I tihnk this is what you want to do?>> a = [1 2 3 4];b = [1 2 4 5];c = ones(4,4);c(1,:) = a; c(:,1) = b;for i = 2 : 4    for j = 2 : 4        c(i,j) = c(i,1) + c (1,j) + c(i,1) * c (1,j);    endend>> cc =     1     2     3     4     2     8    11    14     4    14    19    24     5    17    23    29
