I have a column with 24 rows as attached in the file 'DATA.xlsx'. I want each row to repeat 20 times one after the other i.e.first and second element in the given column is 23, 45 and so on. The new column should contain 20 rows of 23 then 20 rows of 45 and so on keep repeating. How can this be done? Thanks and regards, Parth

Let your present 24 x 1 column vector be called x.
x2 = reshape(repmat(x.’,20,1),[],1);

A simpler method than Roger's
x2 = repelem(x, 20)
