Matlab has a number of functions that help the programmer perform a certain task in a simpler way. In this publication, you'll study a useful element in Matlab programming, which is for the cycle. It is a conditional iteration used in the encoding language.
For loop in Matlab, Check the applicable condition and perform the job according to the given statement that can be repeated multiple times. This work will continue until it meets the requirements. For the loop, it is also referred to as a 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 predetermined, you can use this loop. There are many ring structures in Matlab that begin with the keyword such as "when" or "a" and end with the words "end". The phrase for loop is encoded around certain series of sentences.
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 loops it is necessary to run a certain program multiple times. But you want to leave the program; If you want to skip the next instructions and start repeating the next one, you can use the follow-up statement. A single-column vector can be repeated by using the switch statement to create a row vector.
