You cannot define a function with fixed inputs. The input arguments must be variables:

function num = match(image1, image2)
...

Then you call this from the command window or another function by:

num = match('SIFT REFF.jpg' ,'SIFT TEST.jpg')

These are the very basics of defining a function. Reading the "Getting Started" chapters will be very useful for you.
