MATLAB has a number of features that help the programmer accomplish a particular task in an easier way. In this publication you will learn a useful element in the programming of Matlab, that is, the cycle. This 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 a statement that can be repeated several times. This work will continue until you fulfill the requirement. For the loop, it is also called a variable loop, because it allows the loop to show the sequence of each iteration.
What is for loop in Matlab
The for loop in Matlab allows programmers to repeat some commands. Therefore, if you want to repeat some actions in a predetermined way, one can use this cycle. In Matlab, there is a lot of ringing structure that starts with the keyword "when " or "to " and ends with the words "End ". The cycle phrase is encoded around several 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 a loop it is necessary to run a certain program several times. But you want to exit the program; If you want to move on to the next instructions and start repeating the next, you can use the subsequent statement. A single-column vector can be repeated using the toggle operator to create a line vector.
