Here is a syntax.

>> A = [1 1 3 4 5];

>> To find the square of vector A.

>> A.^2

       = [1 1 9 16 25]

>> To find the cube of vector A.

>> A.^3

       = [1 1 27 64 125]
The Result on MATLAB display:

4. Square Root of the Vector:

Sqrt method is used for calculating the square root of the vector elements. Example: How to find the square root of the Vector in MATLAB? Here is a syntax.
>> X = [2, 4, 1, 7, 8];

>> sqrt(X)

     = [1.4142 2.0000 1.0000 2.6458 2.8284]
The Result on MATLAB display:

5. Minimum or Maximum element of the Vector:

min and max syntax use for calculating the minimum and maximum elements of the vector. Example:
