Thank you,i use:

assignin('matlab', 'Fs', Fs);

i get all this errors

??? Error using ==> input

Not enough input arguments.

Error in ==> Interface_Entrada>input5_editText_Callback at 114

if (isempty(input))

Error in ==> gui_mainfcn at 96

feval(varargin{:});

Error in ==> Interface_Entrada at 42

gui_mainfcn(gui_State, varargin{:});

Error in ==>

@(hObject,eventdata)Interface_Entrada('input5_editText_Callback',hObject,eventdata,guidata(hObject))

??? Error while evaluating uicontrol Callback

??? Error using ==> input

Not enough input arguments.

Error in ==> Interface_Entrada>input8_editText_Callback at 147

if (isempty(input))

Error in ==> gui_mainfcn at 96

feval(varargin{:});

Matrix dimensions must agree.

I use that but maybe there is something else wrong

here is the full code:

function varargout = Interface_Entrada(varargin)

% INTERFACE_ENTRADA M-file for Interface_Entrada.fig

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

% singleton*.

%

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

% the existing singleton*.

%

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

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

%

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

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

% applied to the GUI before Interface_Entrada_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

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

%

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

% instance to run (singleton)".

%

% See also: GUIDE, GUIDATA, GUIHANDLES

% Edit the above text to modify the response to help Interface_Entrada
