I don't understand how to use fitlm if indeed that's the right function to use.
I want to fit 5 sets of data to the function y = ax^2 + bx + c.
tbl = table(Y,X); yes?
mdl = fitlm(tbl,'model') what do I use for model?

If MATLAB itself crashed and shut down completely, then call the Mathworks.
If it's just your script that throws an error with red text in the command window, then most likely there is a problem with your m-file. Post your data with the paper clip icon, along with code to read it in and call the polyfit() function.
I'm attaching my polyfit demo - perhaps you can adapt it.
