Hello,
I have a set of data, organized into four matrices (Length, Elevation, Latitude, Longitude). I am able to reduce the density of the latitude and longitude data using reducem, but I would like to apply the same filter to the length and elevation information so that the relations between each entry are preserved.

You first have to get the indices of which elements are preserved. With those you can construct new elevation, and length vectors. Something like this:
[lat2,lon2] = reducem(lat,lon);
[~,idx] = intersect(lat,lat2,'stable');
elevation2=elevation(idx);
length2=length(idx);
