depends on what you want to do? How do you want to make the conversion. Do you require daily average, daily maximum, daily minimum, value at noon each day, ....

Hi Abdulla,
You may wanna have a look at reshape() function.
Put your data in a column, (apparently its a vector now)
data = data(:); this is one way to make a single column
Than you can reshape your column to a matrix of 360 X N if you like. However 8760 does not generate an integer if divided by 360, so I suggest you pad your data first of all with required number of zeros.
So finally you will have a 360xN data where N is the number of years (about 25 years of data). But keep in mind you will end up with a Matrix.
Hope this helps.
