Hi everybody,
although I looked a little in past questions, I don't seem to find anything suitable. I am confronted with the problem of reducing the sampling rate of a set of files, if possible with a variable reduction factor. For example setting reduction := 60 I would then have a value every minute, instead of a value every second, and so on. All my attempts are baffled by error: "insufficient memory for the required operation".
I built an example with a limited amount of data, in order to show what I am trying to do. But the real files that I have got can reach 1.5 Millions of lines. They are also not readable with Excel.
Moreover, the procedure seems to me very slow. There has to be a better approach, but at the moment I cannot see it.
Thanks a lot in advance for any hint!
Regards
Claudio
PS: a small collateral question would be if there is some easy Mathcad-way to convert the time stamp "hh:mm:ss" in a normal number (like for example seconds from midnight or so).
