Hi Everyone,

Could you please help to speed up this piece of code? What it does, it basically converts 50 Hz data to a 5 Hz data, averaging each 10 values of each field. Second and last field names are not under this conversion. And the last # of values of each field is less than ten, therefore , I use last two lines inside the loop to take care of it.

so, in total there are 11 fieldnames, each containing 12666529 values

tic

for n = [1, 3:length(names)-1]

` for k = 0:count data.(names{n})(k+1) = mean(data.(names{n})((1+10*k):(10*(k+1)))); end data.(names{n})(count + 2) = mean(data.(names{n})(total - (total - (count+1)*10 + 1):total)); data.(names{n})(count+3:total) = []; tocend`

The time I spent right now is 304 secs:

each loop takes around 25 secs

Elapsed time is 25.251421 seconds.

Elapsed time is 50.271446 seconds.

Elapsed time is 75.096751 seconds.
