Illustration of Input in a for loop:
In this illustration, the loop variable iv iterates through the values 1 through 3, therefore the action is repeated three times. The action holds of prompting the user for a number and echo printing it with one decimal place.
Rather than of simply echo-printing the numbers, it is frequently necessary to store them in a vector. The one way of accomplishing this is to begin by preallocating the vector and then putting the values in each element, as we saw in earlier example. Here is a function which does this, and returns the resulting vector. The function receives input argument n, and repeats the procedure n times.
Here is an illustration of calling this function and storing the resulting vector in a variable known as the myvec.
>> myvec = forinputvec(3)
Enter a number: 44
Enter a number: 2.3
Enter a number: 11
myvec =
44.0000 2.3000 11.0000
WHILE Loops: The while statement is used as a conditional loop in MATLAB; it is used to repeat an action whenever ahead of the time it is not known how many times the action w
Index vector: The index vector is then used as the indices for original vector. To get grades vector in ascending order, the indices used would be grades (2), grades (5), and
Properties of the text box - graphics objects: By using get will show properties of the text box, the illustration is as shown below: >> get(thand) BackgroundColor
Sorting Strings: For the matrix of strings, the sort function works exactly as formerly for numbers. For illustration, >> words = char('Hi', 'Hello', 'Howdy', 'Goodbye', '
Opening and Closing a File: The Files are opened with the fopen function. By the default, fopen function opens a file for reading. If the other mode is preferred, a permission
Example of Nested functions: For illustration, the function below computes and returns the volume of a cube. Three arguments are then passed to it, for the width and length of
Example of Functions which return values: Calling this function prints the circumference, since there is no way to store the value, hence, it can be used in following computat
Generic code for Reading from Files: The generic code to complete this is as shown below: fid = fopen('filename'); if fid == -1 disp('File open not suc
Indexing: The Indexing is an alternate to sort a vector. With indexing, the vector is left in its original order. An index vector is used to point values in the original vecto
Steps for input output functions - Lower level file: The steps involved are as shown below: Open the file. Read the file, write to the file, or append to the file.
