M-filesYou will need to be familiar with creating, editing and executing M-files.This allows you to. Store commands for later use. Will you remember in Week 10 the commands you used in Week 2?. Build up larger and more complicated programs. Use the MATLAB editor to debug and then optimize your program.M-files are just plain text files containing MATLAB commands.
An M-file has extension.mfor example cubic.m.An M-file is executed, that is all the commands within the M-file are executed,simply by typing the name of the file (without the.m extension) in the command window.
