Extract the bigger number of values from the previous one in an array

Dear experts,

I want to do this kind of loop

Data = rand(1,15);
for i=1:15
    if Data(i) < Data(i+1)
        X =10;
    else
        X=0;
    end
end
X;

I suppose to get 15 values of X between 10 and 0 but I obtained this error

Index exceeds the number of array elements. Index must not exceed 15.

how can i proceed this loop into

There can't be 15 values, because when i=15, Data(i+1) doesn't exist.

Easier to do,

Data = rand(1,15)

Data = 1×15

0.5961 0.1403 0.0904 0.4693 0.6848 0.1834 0.0516 0.4032 0.2979 0.5497 0.9613 0.9228 0.9208 0.8610 0.7979

X=10*(diff(Data)>0)

X = 1×14

0 0 10 10 0 0 10 0 10 10 0 0 0 0
