I would like to generalize the following codes for dimension D=2:
D=2;dim=factorial(P-1+D)/(factorial(P-1)*factorial(D)); indexes=zeros(dim,D);s=0;for i=1:P for j=1:i s=s+1; indexes(s,:)=[i-j,j-1]; endend
dimension D=3:
D=3;dim=factorial(P-1+D)/(factorial(P-1)*factorial(D)); indexes=zeros(dim,D);s=1;for i=1:P for j=1:i for k=1:j indexes(s,:)=[i-j,j-k,k-1]; s=s+1; end endend
P can be an arbitrary integer (e.g. P=4).
In other words I would like to create D for loops in such a way that the first loop goes from 1 to P (i=1:P) the second loop from 1 to the previous one (j=1:i) the third one from 1 to the second one (h=1:j) etc.
Thank you in advance.
