[Scilab-users] CsvRead function

[Jan Åge Langeland]

csvRead is quite strict regarding column structure etc, but the 
associated error message is typical "can not read......". So when it 
reports "does not exist", it looks like the file is missing, or 
misplaced. If you still think the file is there, you may try this script 
that I have used to check csv files:

//Read CSV file -JÅ 2020
datafile="test.csv";
separators=[ascii(9),";"];
decimal=",";
headerlines=2;
linestoread=-1;// -1 for all
footerlines=2;
fid  =  mopen(datafile,'rb');
csvline=mgetl(fid,linestoread);
mclose(fid);
clear  dataset;
n=size(csvline,1);
for  k=1:n
     if  k>headerlines  &&  k<n-footerlines+1  then
        datatemp=strtod(strsplit(csvline(k),separators),decimal);
        dataset(k-headerlines,1:length(datatemp))=datatemp;
     end
end

disp(csvline(1:headerlines))
disp(dataset)
disp(csvline(($-footerlines+1):$))
