Fucntion input Varargin, value or name.

Im trying to load data from an IMU, but I struggle interpeting what i need to use as input for varagi parmater.

Can anyone explane what i have to type inn her,

Imu = loadImu( FileName, varargi(What do i need to write here?))

Example of the code i want to load,

    function [ Imu ] = loadImu( FileName, varargi)
    %%Arguments
    MASTER = 'RA';
    option = 'sync';
    FsOut = 512;
    nVarargs = length(varargin);
    for iArg = 1:2:nVarargs

    if      strcmp(varargin{iArg}, 'Master'), MASTER = varargin{iArg+1};

    elseif  strcmp(varargin{iArg}, 'option'), option = varargin{iArg+1};
    elseif  strcmp(varargin{iArg}, 'Fs')

        FsOut = varargin{iArg+1};

        resampleData = 1;

    else error('Invalid argument.');

    end
  end

Assuming that the first line of the function is

function [ Imu ] = loadImu( FileName, varargin)

and not

function [ Imu ] = loadImu( FileName, varargi)

as you have written, then you can call it with

Imu = loadImu(somefilename);
%or
Imu = loadImu(somefilename, 'Master', somevalue)
%or 
Imu = loadImu(somefilename, 'option', somevalue)
%or
Imu = loadImu(somefilename, 'Fs', somevalue)

or any combination of the extra arguments in any order

I suspect that is a typo in the file, and the second element in the input argument list should be "varargin" not "varargi".

But I don't know what this function expects as its second, third, etc. input arguments. You'd need to ask the person that gave you that code, and ask them to add some help text indicating what it expects and/or can accept. From the if / elseif structure in the code it accepts parameter names 'Master', 'option', or 'fs' but I don't know what the values of those parameters should be.
