replacing values from a separate vector to multiple repeated values in another vector

I have a vector in the form of

x = [1 0 0 0 0 0 0 1 0 1 0 0 0 0 1 1 0 0 1 0];

and another vector resulted in from data manipulation,

y = [7.83 9 3.2 15.2 3.3];

I want these two vectors to produce another vector (replacing all 0s),

z = [0 7.83 7.83 7.83 7.83 7.83 7.83 0 9 0 3.2 3.2 3.2 3.2 0 0 15.2 15.2 0 3.3];

I started the code by getting the complement of vector x.

Appreacite any help.

index=find(x==0);
idx=find(diff(index)~=1);
z=x;
z(z==0)=repelem(y,[idx(1) diff(idx) numel(index)-idx(end)]);
z(z==1)=0

Works like a charm.

Thanks again Ravi.
