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 failed for me
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
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
