filter

Started by brandon_etheridge November 20, 2002
I am trying to filter a column of values to obtain a smooth curve.
What is the best method in Matlab to filter these data points. I
seem to run into a problem because I am not filtering a function but
rather a column of values.

Thanks in advance,
Brandon



Try using sptool (which stands for signal processing tool). It offers great
flexibility in designing any type of digital filter.

If you are fairly acquainted with matlab then, I suggest you to work at command
line. If you have large number of data to be filtered sptool become pain in the
neck (as it involves many mouse clicks and continous staring at the screen).

If you are interested, I will pass on one of the small mfile which, I created
for filtering purpose.

Hope this helps,
