Hi everyone, I kindly ask you for help for a problem that I am facing, basically I have hourly data of active power produced by photovoltaic systems.
I would like to broaden the resolution of this data, transforming it from hourly to quarter hourly with some sort of fitting or interpolation.
How can it be done? is there any function on matlab that can help me?
Here is an example excel file.
Thanks in advance for your help.
