dataset expansion keeping same values

Is it possible to extend a data in the same fashion as c=1 2 3 4 5 to c1 = 1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 4 4 4 4 4 5 5 5 5 5 but on a much larger scale from an array of 144 to an array of 1440

To transform myArray by repeating its elements nRepeat times:

myArray = 100*rand(1,144); % fake data
nRepeat = 10;
myArrayRepeat = reshape(ones(nRepeat,1)*myArray,1,nRepeat*length(myArray));

or since Matlab R2015a:

myArrayRepeat = repelem(myArray,nRepeat);
