Copying of all channels into matlab workspace (as possibility for matlab users)

Download matlab function and example of using:

https://drive.google.com/drive/folder...

function [numberchannels,nameschannels,tomatlab]=pssout2matlab(inputfile)

nameschannels=[];

channelsdata=[];

numberchannels=[];

tekst=[];

if nargin==0

[filename]=uigetfile('*.out','PSSE .out files'); % select file from disk (without inputfile in function call)

fid=fopen(filename);

else

fid=fopen(inputfile');

end

setstr(fread(fid,4,'char')');

setstr(fread(fid,4,'char')');

setstr(fread(fid,4,'char')');

numberchannels=fread(fid,1,'float32');

fread(fid,1,'float32');

nameschannels=setstr(fread(fid,[32, numberchannels] ,'char'))';

nameschannels=strvcat(strcat('Time',blanks(28)),nameschannels);

tekst=setstr(fread(fid,[60, 2] ,'char'))';

channelsdata=fread(fid,Inf,'float32');

kolona=(size(channelsdata,1)-2)/(numberchannels+2);

rezultat=reshape(channelsdata(1:kolona*(numberchannels+2)),numberchannels+2,kolona)';

tomatlab=rezultat(:,2:size(rezultat,2));

fclose(fid);

numberchannels=numberchannels+1;

nameschannels=strcat(num2str([1:numberchannels]','%06.f'),'-',nameschannels);

end

Thank you for your wonderful tool jconto! After adding the necessary libraries, all of the example functions in "testall.bat" were able to run except the damping ratio example "chanPe_dmp.ini". I found that the reason for this was the version of the Pandas library. I had installed Pandas using "pip install pandas", which installed the most recent version (v2.1.4). However, the Channels tool relies on the pandas "append" attribute which is depreciated in Pandas 2.x, which uses the attribute "concat" instead of "append" (https://stackoverflow.com/questions/7...). I uninstalled Pandas, then reinstalled using "pip install pandas==1.5.3" and then the damping ratio example worked. Posting here so that others can resolve the issue more quickly than I did.

Thanks again for sharing your hard work!
