How can I take multiple selections from four listboxes and initialize the selections to varargout to be an output of the function? The error my code throws is at the bottom of my code.

function varargout = ConfigurationsAndSimulationDetails(varargin)

% CONFIGURATIONSANDSIMULATIONDETAILS MATLAB code for ConfigurationsAndSimulationDetails.fig

% CONFIGURATIONSANDSIMULATIONDETAILS, by itself, creates a new CONFIGURATIONSANDSIMULATIONDETAILS or raises the existing

% singleton*.

%

% H = CONFIGURATIONSANDSIMULATIONDETAILS returns the handle to a new CONFIGURATIONSANDSIMULATIONDETAILS or the handle to

% the existing singleton*.

%

% CONFIGURATIONSANDSIMULATIONDETAILS('CALLBACK',hObject,eventData,handles,...) calls the local

% function named CALLBACK in CONFIGURATIONSANDSIMULATIONDETAILS.M with the given input arguments.

%

% CONFIGURATIONSANDSIMULATIONDETAILS('Property','Value',...) creates a new CONFIGURATIONSANDSIMULATIONDETAILS or raises the

% existing singleton*. Starting from the left, property value pairs are

% applied to the GUI before ConfigurationsAndSimulationDetails_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to ConfigurationsAndSimulationDetails_OpeningFcn via varargin.

%

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

% instance to run (singleton)".

Answer 1

[Image Analyst]

Get rid of the braces {:}

varargout = [powertrainArray, engineArray, motorArray, batteryArray]

Make sure each of those is a row vector or if they're column vectors, make sure they all have the same number of rows in them.

Or have it be a cell array like

varargout = {powertrainArray, engineArray, motorArray, batteryArray}

Actually, this may be better since it keeps the arrays separate - each array in its own cell.

[Brandon McDonald]

I tried the curly brackets you suggested and got the same error.

I tried the regular brakets and got this error now:

Variable output array "varargout" must be a cell array.

Error in ConfigurationsAndSimulationDetails>closingfnc (line 226)

function varargout = closingfnc(powertrainArray, engineArray, motorArray, batteryArray)

Error in ConfigurationsAndSimulationDetails>pushbutton1_Callback (line 223)

closingfnc(powertrainArray,engineArray,motorArray,batteryArray)

Error in gui_mainfcn (line 95)

feval(varargin{:});
