Octave commands can be saved in a file and evaluated by loading the file using source
.
For instance, let hello.m
be the text file containing two lines (the first line is a comment)
# my first Octave program
disp('Hello, World!')
If you type source hello.m
at an Octave command prompt you will get
>> source hello.m
Hello, World!
Note that a script file doesn't necessarily have to have the extension .m
.
