MATLAB: How to build ratio between two columns of a matrix

matrixratio

I have a matrix of size 102 x 2555 I want to select each column from 1 to 2555 of this matrix and then divide to each column of this matrix. For example: I have matrix
A=
   1 2 3 4 5 6
   2 3 4 5 6 7
   3 4 5 6 4 6
   5 6 8 7 1 3
I want to build the ratios like this:
ratio1=column1./each column in matrix A
ratio2=column2./each column in matrix A
ratio3=column3./each column in matrix A
….
ratio6=column6./each column in matrix A
Thanks for your help!

A= ...
   [1 2 3 4 5 6; ...
   2 3 4 5 6 7; ...
   3 4 5 6 4 6; ...
   5 6 8 7 1 3];
[nrow,ncol] = size(A);
for n = 1:ncol
      ratio{n} = bsxfun(@rdivide,A(:,n),A)
end
