How do I plot a 3D mesh from multiple csv files?
Here is the code I've been using, found from the internet:
nFiles=101
filenamePrefix='F1--Trace-no loop-0000--0000';
filenameExtension='.csv';
for i = 1:nFiles
filename = [filenamePrefix, int2str(i), filenameExtension];
tmpData=load(filename,'-ascii');
x{i}=tmpData(:,1);
y{i}=tmpData(:,2);
end
mesh(x{i},y{i},i}
This is the error I recieved:
Error using load
Number of columns on line 2 of ASCII file F1--Trace-no
loop-0000--00001.csv must be the same as previous lines.

The problem apparently is with loading the files, nothing to do with plotting 3d mesh, or at least it didn't get far enough to have any problem with that. It is difficulat to tell exactly what is causing the problem without seeing the files you are trying to load.
I think that it is likely that the first line is a header and has a different number of columns
You could try
tmpData = readmatrix(filename, 'NumHeaderLines',1)
