Collected data values for the desired lat long need to put in the variable temp_file. Therefore, what I expect temp_file should be populated with all the data values(from spd variable) corresponding to the lat long in 'loc' variable. Here the loop of j and k completes when j and k run from loc(1,0) to loc(1,1) and loc(0,0) to loc(0,1). Once the data has been collected in temp_file, next target is to take average of all the data and put it in the variable final_spd. Here average value is put in the variable temp_avg. The same iteration needs to do for 48 different times. </div><div class="gmail_default" style="font-family:verdana,sans-serif"><br class=""></div><div class="gmail_default" style="font-family:verdana,sans-serif">Here what I noticed the loop of j and k each time filled the temp_file with a single value upto its dimension 30 and each iteration of j and k did the same task. Therefore, instead of taking average over various data value corresponding to different lat long it takes average on a single value that arises during the last iteration and put it in the final_spd variable. </div><div class="gmail_default" style="font-family:verdana,sans-serif"><br class=""></div><div class="gmail_default" style="font-family:verdana,sans-serif">What I want is to take all the data corresponds to the j and k loop corresponding to a particular time (represented by i loop) and take the average over those data and put it in the final_spd variable and need to do the same task for next 47 hours and put the average in final_spd variable.
