为什么会发生此错误：索引超出矩阵尺寸

Question

I am running a GUI system in MATLAB and I am a beginner with working with GUI's.

The code is extensively long and so I am going to just put in what and where I have things and see if it is enough information for help to be given, thanks.

in my first GUi I have this in the opening function:

HW12_result_bhanford(handles.scan_age, handles.check_athlete, handles.radio_male, handles.radio_female)

this is supposed to be transferring these four variables over to my third GUI named HW12_result_bhanford

In my second GUI I have this written in the opening function:

age = varargin{1}
athlete = varargin{2}
male = varargin{3}
female = varargin{4}

I then use these four variables(age, athlete, male, female) later in the second GUI and I assume them to be the equivalent value of the corresponding variable passed from the first GUI. When I run everything the error that comes back is Index exceeds matrix dimensions.

if anyone could help me, that would be awesome. If you cannot help without the entire code I understand.

Answer 1

You use varargin if your argument list is variable, and varargin has to be in your function definition.

function HW12_result_bhanford(varargin)

In this case function receive a cell array as an input, so you can get individual arguments with varargin{1} etc.

If you put your arguments together as a structure, you can pass this structure as an argument along.

function HW12_result_bhanford(handles)

But if the function definition has individual arguments, for example,

function HW12_result_bhanford(age, athlete, male, female)

you cannot use varargin , just process the arguments as is.
