I have rainfall data in .mat format. Data is 2D matrix mxn where m are row representing m days and n is column representing n locations. I wanted to calculated SPI for each location as well as whole country. Please do not suggest any softweaer.

They're fitting multiple distributions to find best fit of precipitation data over the given time period, then using that to compute a percentile.
Search the FileExchange; there are several submissions there that should at least give you a head start...this won't be a five-minute exercise.
