How to Use For Loop in MATLAB

A number of functions that help a programmer to perform a particular task in an easier way. In this publication you will learn a useful element in Matlab programming, i.e. for the loop. This 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 A statement that can be repeated several times. This work will continue until it is not required. The loop is also called the loop variable because it allows the loop to display the sequence of each iteration.

What is for loop in Matlab

The loop for Matlab gives programmers a repeat of some commands. Therefore, if you want to repeat certain actions in a predetermined manner, you can use this loop. There are many ring structures in Matlab that begin with the keyword such as "when ", or "up to/" and end with words "End ". The loop expression is encoded around several expression groups.

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

You can use "for loop/" To repeat certain actions, or we can say that for a loop it is necessary to run a particular program several times. But you want to get out of the program; If you want to jump through the following instructions and start repeating later, you can use the tracking statement. You can repeat a single-column vector by using the switch declaration 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.
