How to replace some elements from a vector using if

Hello everyone!

If i have a vector, lets say L=[10;10;10;11;11;13;13] which is associated to another vector X=[1;6;65;34;21;73;14] and I want to create a third vector, Z, with almost all the elements in X, but just replacing a 0 in X when the element (i,j) from L changes. Lets say that the result that I want should look like this Z=[1;6;65;0;21;0;14]

Any ideas how to solve this?

I would be really thankful :)

[~,jj]=unique(L)
out=X;
out(jj(2:end))=0

Thanks Azzi but this is giving me the next vector

Out=[1;6;65;34;0;73;0] and not Z=[1;6;65;0;21;0;14]

any suggestions?

Thanks
