Hello everyone, I started using Julia recently and am very pleased with the many options I am given to write code. Now I want to translate a toolbox I wrote in MATLAB to Julia (It's about MRI reconstruction).
There are often lots of options in my function arguments, something which I handled in a quite ugly way in Matlab, for example: A function which loads an image takes in a filename and varargin, where varargin can be certain counters I need to construct a matrix from binary data. If no varargin is supplied, the function calls another function which will load these counters from a seperate header file. If they are supplied, it expects them to be correct and in the right order to function. Now in Julia I have the option to specify all the variables needed in the arguments, and give them default values. The default, however, depends on the file which I am loading - if the extra arguments are not supplied, I would call the other function which gives me the defaults. Does anyone know an elegant way to handle this in Julia? I thought of making keyword arguments which I could all set to 0. Then I can check that at the beginning of the function and load the defaults if necessary. But that seems ugly to me. I put some example code here: https://gist.github.com/timlod/7bb82e4796dd6404ccfa If this is too vague, I'll try to concretise it more :) Thanks, Tim
