Hello, I have a vector of 8760 values, representing hourly solar irradiance per one year. I need the irradiance "per second" (so moving to 31536000 values). I can do it by interpolation but is a quite rough method, too approximated. I want to introduce some randomness. Ideas?

what about using interp() and then just adding some randomness by addition or subtraction?

d = rand(3600, length(flux_per_hour));
rd = d./sum(d,1);
flux_per_second = flux_per_hour(:).' .* rd; %seconds down, hours across
flux_per_second = flux_per_second(:); %consecutive seconds
