I have a time series which has vector values recorded at a frequency greater than 1 hz (1 measurement per second) with uneven intervals and I would like to average the vector values for each second so that I effectively have a time series with a 1 hz frequency.
Is it possible to create a loop with variable increments to achieve this? Or might ACCUMARRAY be more suitable?
Here is an example of my data set.
Time SO4 77237.3 0.165 77247.3 0.177 77276 0.137 77304.4 0.093 77304.4 0.093 77332.8 0.103 77361.3 0.072
Any help would be greatly appreciated. Thanks

One possibility is to use 'interp1' set to interpolate at some appropriate multiple of one hertz, say, 20 Hz. You can select the type of interpolation that best suits your data. Read the documentation at
Then take a straightforward average over each twenty (or whatever multiple you choose) points to get the average for the corresponding second.
