**^**operator; however, the exponentials of a scalar or an array can be calculated using the built-in

**exp()**function.

This tutorial is going to discuss different examples of how to work with powers and exponentials of a scalar, matrix, vectors, or an array in MATLAB.

**1: How to Take Power in MATLAB**

Taking power in MATLAB is a useful task regardless of whether you are taking the power of a scalar, array, or matrix, all and all you have to use the **^ **operator for this operation. The **^ **operator computes any positive, negative, and fractional powers of a number within no time. The **^** operator is a piecewise operator which means it is applied to each element of an array individually using the **.^** operator instead. The same case applies to calculating the power in matrices, vectors, and multidirectional arrays as well.

**Example 1: How to Calculate the Power of a Scalar in MATLAB?**

This MATLAB code computes the positive, negative, and fractional powers of the given number using the **^ **operator.

ans1 = num^2

ans2 = num^(-2)

ans3 = num^(1/2)

**Example 2: How to Calculate the Power of a Square Matrix in MATLAB?**

In this example, we calculate the positive, negative, fractional, and element-wise powers of the given square matrix.

ans1 = A^3

ans2 = A^(-3)

ans3 = A^(1/3)

ans4 = A.^3

**2: How to Use Exponentials in MATLAB**

Taking exponentials is another common task widely used in MATLAB programming. We can calculate the exponentials of a scalar, vector, matrix, or multidimensional array using the built-in **exp()** function. This function takes a number or an array as an input argument and provides its calculated exponential in return.

**Syntax**

In MATLAB, you can use the **exp()** function in the following way:

exp(X)

**Example 1: How to Calculate the Exponential of a Scalar in MATLAB?**

In this MATLAB code, we use the **exp()** function to compute the exponential of the given number.

exp(num)

**Example 2: How to Calculate the Exponential of an Array in MATLAB?**

In this example, we calculate the exponential of the given array using the **exp() **function in MATLAB.

exp(X)

**Conclusion**

MATLAB is a beneficial programming tool that allows us to perform many tasks. It enables us to compute the powers and exponentials of a scalar or an array using the **^ **operator and **exp() **function, respectively. This guide has provided beginner-level instruction to help users calculate the powers and exponentials in MATLAB for a matrix, vectors, or multi-dimensional arrays.
