Exercise 1: List the MATLAB command to start Guide with an existing project name

Question

Exercise 1: List the MATLAB command to start Guide with an existing project named 'myGUI'.

Exercise 2: Explain the differences between a function, a subfunction and a nested function.

Exercise 3: When using Guide what are two ways to bring up the object inspector?

Exercise 4: In a Guide developed GUI describe the three parameters to a callback function.

Exercise 5: What GUI object parameter do you change in order to change the name of the object within your code.

Exercise 6: From within a Guide developed GUI callback function, how would you change the text shown on a static text object named 'mass' when the callback is executed.

Exercise 7: What parameter do you define for a GUI object to have it change size as the user changes the size of the window?

Exercise 8: Copy the entire function handle associated with the unitgroup Button Group widget for SelectionChangedFcn in the guide GUI with uicontrols sample.

Exercise 9: List what items are in the Tools menu within GUIDE and what is their function.

Exercise 10: List the names of all widgets (controls) that you can add to the GUI on the guide tool pallet on the left side.

Explanation / Answer

Hi,

TabPanel Constructor offers the easiest way for creating of tabpanels in MATLAB!

- No programming is necessary!
- All tabpanels can be edited comfortably with GUIDE!
- All MATLAB UI controls are supported.
- result is the original FIG-file and the accompanying M-file which is automatically extended with callbacks
- No ActiveX or JAVA components are used!

What Are Nested Functions?

A nested function is a function that is completely contained within a parent function. Any function in a program file can include a nested function.

For example, this function named parent contains a nested function named nestedfx:

The primary difference between nested functions and other types of functions is that they can access and modify variables that are defined in their parent functions. As a result:

A nested function is literally defined in the middle of another
function and requires end statements:

Here is a example of a nested function:
function t = test()
x = 1
   function t1 = intest(t)
      t1 = t + 10
   end
y = intest(x)
end

Here is the same code as a subfunction:
function t = test()
x = 1
y = intest(x)

function t1 = intest(t)
t1 = t + 10

You must be careful with scope in nested functions as all variables
in the parent function are global to the nested function.

Here i am posted whatever i Know.

Please give me good rating.

Thanks in advance

Nested functions can use variables that are not explicitly passed as input arguments.

In a parent function, you can create a handle to a nested function that contains the data necessary to run the nested function.

Requirements for Nested Functions

Typically, functions do not require an end statement. However, to nest any function in a program file, all functions in that file must use an end statement.

You cannot define a nested function inside any of the MATLAB
