Hi Paul this is very usefull. Thanks! I often work with parameter stepping. I observed that LTspice2matlab does not cover this feature. It outputs all steps sequencially without notifying that it is stepped data and providing info about about runs. This would a be nice feature for the next version.

This is fantastic! I struggled with Helmut's ltsputil.exe program for a while, intending to bring the final results into Matlab and this program does all that in 1 step.

This failed for me

LTspice2Matlab('test.raw')
Error using LTspice2Matlab (line 212)
Format error in LTspice file "/Users/acurtis/Desktop/test.raw" ... Wrong number of
columns in the variable define section

I created the raw file from an example circuit netlist I got from

http://www.ngspice.com/examples.php

I chose the "RC filter AC response" and copied the netlist to a file. I ran ngspice with the command

ngspice --batch --rawfile="test.raw" "rc.net"

and then in MATLAB

LTspice2Matlab('test.raw')
