% Read matrix
X=pascal(3);
disp(X);
[r c]=size(X);
i=1;
%while i==c
for j=1:c
    z=[X(i,j);X(i+1,j);X(i+2,j)];
    disp(z);
end
i=i+1;
%end
breaks=[0 4 8 12];
pp=mkpp(breaks,X);
%ppn=vertcat(pp);
ppn=cell2mat(struct2cell(pp));
a=polyvalm(X,pp);

Best Answer

coefs = pp.coefs ;
breaks = pp.breaks ; 
peices = pp.pieces ; 
order = pp.order ; 
dim = pp.dim ;
