How to Use For Loop in MATLAB

Matlab has a number of functions that help the programmer perform a particular task in an easier way. In this publication, you'll study a useful element in Matlab programming, that is, for the loop. It is a conditional iteration used in the language of coding.

For loop in Matlab, Check the applicable condition and perform the job according to the given 

statement that can be repeated several times. This work will continue until it does not meet the requirement. For the loop, it is also referred to as the loop variable because it allows the loop to show the sequence of each iteration.

What is for loop in Matlab

The for loop in Matlab gives programmers to repeat some commands. Therefore, if you want to repeat some actions in a predetermined way, one can use this loop. There are many ring structure in Matlab that start with the keyword such as "when", or "to" and ends with the words "end". The for loop phrase is encoded around a few sets of phrases.


Some of the examples of For loop in Matlab


Decrement values


In this, the programmer can decrement the values of the defined interval.
Program: 
For a = 3.0 : -1.0 : 0.0
disp(a)
End
This program will execute the value by decrementing by ‘1.0’
The output will be:
3
2
1
0


Increment Values


It will increase the given values by the given number of intervals.
program:
for a = 5.0 : 2.0 : 12.0
disp(a)
end
the output will be incremented by 2:
5
7
9
11
Another example of it is: 
program:
for a = 2.0 : 1.0 : 5.0
disp(a)
End
Now, the output will be increment by the value 1:
2
3
4
5


Specified Values


It will run the statements for specified values
program:
for a = [2 3 5 7] disp(a)
end
This is how the output will represent:
Output:
2
3
5
7


Use of Repeat Statement for every Matrix Column


Here the A is a 3X3 Identity matrix
Program:
for A = eye (3,3)
disp(‘Current value:’)
disp(A)
end
Output:
Current value:
Diagonal matrix: 
1
0
0
Current value:
0
1
0
Current value:
0
0
1


Use of BREAK Statement


To exit from the ‘for loop in Matlab’, the programmers can use the break statement. Without using the break statement, the following example will print the ‘END’ value after each iteration
Program:
for A = eye (2)
disp(‘Value:’)
disp(A)
disp(‘END’)
end
Output:
Value: 
Diagonal matrix:
1
0
End
0
1 
End
If the programmer uses it with a break statement, then it will break the ‘for loop’ after the initial iteration.
Program:
for A = eye (3)
disp(‘Value:’)
disp(A)
break
disp(‘END’)
end
Output:
Value:
Diagonal matrix:
1
0
0
This shows that the statement is the break after the initial statement.


Conclusion


"for loop" can be used to repeat certain actions, or we can say that for loop is necessary to run a particular program several times. But you want to get out of the program; If you want to jump on the next instructions and start repeating the next, you can use the follow-up statement. A single column vector can be repeated using the switch statement to create a row vector.

Still, you are not able to understand the use of for loop in Matlab; then, you can take our experts’ help who can provide you instant help with your MATLAB online help and MATLAB help online. We are also here to provide you the best online MATLAB help.

Know How to Use Switch Case in Matlab

What is the  switch case in Matlab ? The full format of Matlab is Matrix Laboratory, one of the best coding languages used for technical and scientific calculations. This programming language includes an environment for visualizing data, accounts, and logical encryption. It also includes error correction and editing tools that carry factors, and can support the idea of object programming (OOP). These parameters make Matlab heavily used and use these tools for academic research and teaching. You may be familiar with the Concept of Matlab, its core function, data types, and loops. This sharing will provide you with the status details of the switch in Matlab. The switch status statement is used to control the flow logic that can be widely used. You can use several alternatives using if-else statements. This statement can make the code long and corrected and not easy to read. The switch status statement helps programmers determine how many options make the code easy to read, ...
