Need assistance implementing ode45 in GUI

Hey not sure what to do about the errors I'm getting any assistance is greatly appreciated

My code:

function varargout = GUI_Assignment_Zuhs_Carey_Otic(varargin)

% GUI_ASSIGNMENT_ZUHS_CAREY_OTIC MATLAB code for GUI_Assignment_Zuhs_Carey_Otic.fig

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

%      singleton*.
%

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

%      the existing singleton*.
%

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

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

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

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

%      applied to the GUI before GUI_Assignment_Zuhs_Carey_Otic_OpeningFcn gets called.  An

%      unrecognized property name or invalid value makes property application

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

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

%      instance to run (singleton)".

Your funct() is not nested in your func(), so they do not share variables. You should have parameterized like I said before. http://www.mathworks.com/help/matlab/math/parameterizing-functions.html

[t, y] = ode45(@(t,y) funct(t, y, A, B, C, E, F), [0 tmax], [0 0 0]);

with

function ydot = funct(t, y, A, B, C, E, F)
