I asked a similar question last night, but didn't get an answer I understood. To be more specific, I have 366 matrices, each size 72×144, and each representing a day's worth of data, for a total of one year worth of daily data. The file names for the individual matrices are in the format "20040101.txt", "20040102.txt", … "20040131.txt", "20040201.txt", etc. I would like to create a new 72×144 matrix which represents the average by element of the original 366 matrices. What is the easiest way for me to do that, keeping in mind I know very little about MATLAB.
Last night, I successfully made an average matrix for two separate months, but it took me nearly an hour to do so, because I did it the only way I understood: add all matrices manually and divide by 31, such that:
newMatrix=('20040101.txt'+'20040102.txt'…'20040131.txt')./31
How can I make this simpler? I know there is a better way, but can someone please also explain in detail what the simpler function does (how it operates) rather than just giving me the code?
Thanks,
Patrick
