How to fit same variance of data to another data ?

I have two data sets of energy consumption for full day with 30min(data size 48*1) and 1 min(data size 1440*1) time interval of different days.

Now I want to make 30min time interval data in the form of 1min(data size 1440*1) time interval for full day, assuming that the same variation is hppened in load curve pattern both days. Which data statistic method to be applied for this calculation and how to implement it in matlab ?

Thanks

Probablu you need to interpolate the data.....read about interp1

but how can I put the same load pattern of 1min time interval data to 30min time interval data using interpolating data??

It does linear interpolation.

No , I want to do non linear with same pattern/variation of another data set, like using curve fitting.
