I need help. Here's what I'm trying to do. I have signal strength data samples at various lat/long points (some overlapping) over about a 1km^2 area. I need to plot them using a contour or pcolor function perhaps, but need to dump them into a matrix first without creating some looped code. Or maybe that's the way.

Any ideas? Thanks - I'm stuck using MATLAB 6 and am a novice coder at best.

So you have scattered data that you want to grid? Look at GRIDDATA.

Alternately you could use SCATTER to plot them as a scatter plot.
