function varargout = test11(varargin)
% TEST11 MATLAB code for test11.fig
%      TEST11, by itself, creates a new TEST11 or raises the existing
%      singleton*.
%
%      H = TEST11 returns the handle to a new TEST11 or the handle to
%      the existing singleton*.
%
%      TEST11('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TEST11.M with the given input arguments.
%
%      TEST11('Property','Value',...) creates a new TEST11 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before test11_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to test11_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

Answer 1

[Geoff Hayes]

Saurao - I'm going to guess that

set(handles.D,'String',final_D)
set(handles.B,'String',final_B)
set(handles.C,'String',final_C)
set(handles.C0,'String',final_C)
set(handles.Designation,'String',final_Designation)

the D, B, C, C0, and Designation are not valid handles to edit text controls and are probably not even members of the handles struct. This is a guess because you didn't include the full error message and I don't see any CreateFcn or Callback functions in your above code (which would tell us that you have edit controls named as D, B, C, C0 and Designation).

Please confirm that your GUI does indeed have edit controls named as above or use the correct handles.

[Saurao Dalvi]

D,B,C,C0,Designation are the handles(static txt)

[Geoff Hayes]

Saurao - and you have verified that these handles exist? Please confirm that they do as you still haven't posted the error message (if one exists) for when you try to update these static text controls.

However, given the code that you have posted for the ball_bearing function, it appears that

 [final_D,final_B,final_C,final_C0,final_Designation]

are numeric. If that is the case, then you need to convert them to strings before updating the text fields

 set(handles.D,'String',num2str(final_D))
 set(handles.B,'String',num2str(final_B))
 set(handles.C,'String',num2str(final_C))
 set(handles.C0,'String',num2str(final_C))
 set(handles.Designation,'String',num2str(final_Designation))

Please note also that you probably want

 set(handles.C0,'String',num2str(final_C0))

rather than re-using final_C.

Answer 2

[Saurao Dalvi]

Thanks , now it is providing the display in GUI. but the function (ball_bearing) doesn't return value to work space

[Saurao Dalvi]

Given input to ball bearing should be [final_D,final_B, final_C, final_C0, final_Designation]=ball_bearing (0.333,3000,30000,600,40) Ans: final_D=90;

[Walter Roberson]

Functions do not return values to the workspace. You have to assign the output to a variable and look at the variable. You appear to already be doing the assignments.
