Description 
S=MINKSUM(A,B) produces the Minkowski sum of two sets A and B in Euclidean space, the result being the addition of every element of A to every element of B.
[S,D]=MINKSUM(A,B) returns the Minkowski sum S, and also the multiplicity of each element in S.
The number of columns represent the dimensionality. An array of M points in ND space is an MxN array. A vector of 1D values is a column vector.
If the sizes of A and B are MAxN and MBxN respectively, then the size of S will be at most (MA*MB)xN
Example:
A=[1 1; 2 1; 2 2; 1 2]; B=[3 3; 4 3; 4 4; 3 4];
[S,D]=minksum(A,B);
plot(A(:,1),A(:,2),'*',B(:,1),B(:,2),'s',S(:,1),S(:,2),'d')
axis([0 7 0 7])
