- We use MatLab 3.5 on a Mac Quadra, Ethernetted to a KPC Titan running AVS.
- MatLab proved most valuable for its established Toolkits for signal analysis
- and system identification. In 3.5 the graphics are naive, but once we
- processed our data arrays, we could export the results into:
- SerePlot and KaleidaGraph for plotting and conversion
- UNIX files on the Titan where we use AVS for 3-D visualization
- and projection onto photos and topo maps.
-
- The rapid FTP connection between MatLab on a Mac and a very competent UNIX
- box is a dream! (Given that MathWorks no longer supports MatLab on the Titan).
- In that our data arrives in spreadsheet format, we need Excel anyhow.
-
- MatLab is a convenient tool, as is Excel, but I would not want to try to
- complete a major project using nothing else. It takes a while to determine
- which tool can do the task in the best way, then you develop a "style".
- Even Excel can do FFTs, but it's not its forte!
