A small tool to read and write LAS files in Matlab. Limited conversion capacity is also included and modifications/repairs to LAS data structures are possible via direct editing of variables. Supposedly reads all versions of LAS up to 1.4 version. As usual this tool was made for a single project and testing done to it is very light. Can also open LASZ compressed files if you provide the laszip executable (note: it simply decompresses the file automatically, nothing else).
Update note:
Alibity to create empty object ('createemptyobj' constructor parameter) with a empty header (you need to lookup las specification for values & data types).
Loading all variables with constructor parameter ('loadall'). Note full waveform lidar waveforms are not loaded. Use getwaveforms for that.
