Deleting an Element in an Array in Matlab

In this lesson, I will show you how to remove an element from an array in Matlab, using a practical example.

To begin, create an array containing several elements:

>> v=[1 2 3 4 5]
v =
1 2 3 4 5

Next, remove the third element from the array by typing v(3)=[ ].

The position of the element should be specified within the parentheses (3), immediately following the array name.

>> v(3)=[ ]

This command will delete the element from the array, and assigning an empty value [ ] achieves this.

After running the command, the array will have four elements:

>> v
v =
1 2 4 5

This method can be used to remove any element from a one-dimensional array.

However, please note that this command does not work with arrays that have two or more dimensions (such as matrices). It is only suitable for one-dimensional arrays (vectors).
