Thank you all for the very helpful discussion!
Tim,
Interesting to hear about that.
Concerning the best way to write the code, I assume you meant the below?
matwrite(F1, Dict(
“x” => B[:,1],
“y” => B[:,2],
“f” => B[:,3]
); compress = true);
My question is why they use a semicolon, instead of a comma after the dictionary variable? Both seem to work though.
