Octave Power Operator
Octave Power Operator
In this tutorial, we will learn about Octave Power Operator with Examples. We have two operators in Octave that compute the power.
x ^ y
x ** y
The result of the computation depends on the values of the operands x and y.
If both x and y are scalars, then x ^ y returns the result x raised to the power of y.
If x is scalar and y is a square matrix, the result would be eigenvalue expansion.
Examples
^ Operator
Let’s look at a simple example.
>> x = 2;
>> y = 3;
>> result = x ^ y;
>> result
result = 8
The result is 2*2*2 = 8
** Operator
We can also use the ** operator.
>> x = 4;
>> y = 4;
>> result = x ** y;
>> result
result = 256
Element wise Power
To compute element-wise matrix power calculation, we can use the following operator.
x.^y
>> x = 2 ;
>> y = [2, 3; 3 , 5];
>> result = x.^ y
result =
4 8
8 32
