How fill a part of 3D array with decreasing values?

Dear all,

I have a 3D array and I just want to fill a buck of this array with decreasing values, with step i've chosen. The values would decrease only in one direction, and constant on the two others.

For instance i have this : >> N=10; >> X=zeros(N,N,N); >> X(:,:,1:10)=20:-2:2; ??? Assignment has fewer non-singleton rhs dimensions than non-singleton subscripts

Could somebody help me with the syntax please?

Thanks in advance.

Alexandre.

I think you are trying to do something like this

>> a=20:-2:2;
>> for i=1:10
for j=1:10
X(i,j,1:10)=a(1:10);
end
end

Thanks a lot, this is what I was expecting for!
