MATLAB: Argument Question

argumentclarificationMATLAB

I have a homework assignment that says, "Your function will receive the name of the input file as an argument." I'm just a little confused on what that means. Does it means it will be something along the lines of:

function HW = load('data1.txt')

Best Answer

I think this is what they meant -

In the function file:

function outputVar = myfunction(inputVar)
% write the rest of the program here, using inputVar as you would a string

When you call the function you give it a string:

thisoutput = myfunction('data1.txt')

You mention "avoiding" structures, but I would say this is definitely one solution. They are not that difficult to learn. Here is one starting point: http://www.mathworks.com/help/matlab/structures.html

Another possibility, which may or may not be feasible (depending on the size of the variables), would be to write/read the variables to disk, using the save() and load() commands. Maybe not the best programming practice, but easy.

Speaking of questionable programming practices, you could also use global variables. This may be appropriate if the same variable are really shared by a lot of function.
