Interpolation of hourly data into minutes

Hello again, I am having a trouble with modifying my data. I have hourly data of photovoltaic production during whole year, so it's 8760 values. I need to transfer them into minute data => 525 600 values. Here is the sample of first 24 hours values. e.g. value 152.03 will be separated into 60 values of 2.53, 0 into 60x0 and so on..

Can you help me with this? Thank you.

[Andrei Bobrov]

here a - your hourly values.

out = kron(a,ones(60,1)/60)

Thank you very much, works fine.

A slightly smaller example that illustrates the general technique:

y = repelem(1:4, 3)/8

The output is a twelve element vector that you can think of as having four [= length(1:4)] groups of three elements where the first group contains 1/8, the second group 2/8, etc.
