Making Lookup Table from Matlab data sheet

You can either generate a mif(or hex) file using Matlab programming. Alternatively a non-official shortcut is this:

open a new mif file in quartus(you will get cells like spread sheet), set width and size,set data type to signed ...etc.

go to matlab and display your data as column of integers, copy to clipboard then go to quartus mif and paste. In this way quartus does the work for you.

I also commonly use this trick to convert data as well(hex to signed to binary...) and copy back to my work
