Error while evaluating UIControl Callback

Dear

I received the following error messages:

"Conversion to cell from double is not possible.

Error in DWRDataProcessing>pushbutton1_Callback (line 280)

d((k+d_begin),1)=visc(k);

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in DWRDataProcessing (line 44)

gui_mainfcn(gui_State, varargin{:});

Error in

matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)DWRDataProcessing('pushbutton1_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback."

Hope someone can help out! Below I included a copy of the code.

function varargout = DWRDataProcessing(varargin)

% DWRDATAPROCESSING M-file for DWRDataProcessing.fig

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

% singleton*.

%

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

% the existing singleton*.

%

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

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

%

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

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

% applied to the GUI before DWRDataProcessing_OpeningFunction gets called. An

% unrecognized property name or invalid value makes property application

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

%

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

% instance to run (singleton)".

[Adam]

d = {'Corrected viscosity', 'Corrected elasticity','Status:1=converged,0=diverged'};

defines d as a cell array (though apparently not in all paths of the code). You then try to assign a double to this on a following line, hence the error message that you cannot convert from double to cell.

Using the debugger (especially the 'stop on errors' setting) is by far the easiest way to find and understand these problems.

Dear Adam

Thank you for the quick response. Maybe I should have specified that I am able to run the program as it should run. Only in the end, when the program should write the data away to the original Excel sheet does it give the error messages.

Best regards,

Frederik

[Adam]

My point is still the same. In the function that yields the error message you define d as a cell array then try to assign a double to it.

I have removed the bug, please check the latest version of the code (January2020).

I appologize for the inconvenience.
