MATLAB: How to replaces NaN’s with a corresponding vector

vectors

I have two vectors x=[1 NaN 2 3 NaN 4 NaN NaN NaN 5 ]; y=[10 11 11 6 8 9 7 2 29 93 ]; I would like to know if there is a way to replace only the missing values (NaN's) in x with the corresponding value in the vector y?

mask = isnan(x)
x(mask) = y(mask)

 x(isnan(x))=randsample(x(~isnan(x)),1)

Try this:

X=[nan nan 4 3 6 9 2 nan nan nan 8 2 13 6 1 nan];
Y=[9 13];
risingEdgeLocs = find(diff(~isnan(X)) > 0);
indSplit = find(ismember(X,Y));
for i = 1:numel(indSplit)-1
 X(indSplit(i):risingEdgeLocs(i+1)) = nan;
end
X(indSplit(end):end) = nan;
Z = X;
