Hello everyone,
I am trying to write a code that convert a vector like the following for example:
X=[1 2 3];
to a matrix like the following:
Z=[1 0 0 2 0 0 3 0 0;...
0 1 0 0 2 0 0 3 0;...
0 0 1 0 0 2 0 0 3];
Any ideas?
Thanks very much.

X-[1 2 3];
Z=zeros(3,3*numel(X));
for k=1:numel(X)
Z(9*k:-4:9*k-8)=X(k);
end
参考
