Overview

In this tutorial, we will learn about Octave Addition Operator
with Examples.

Octave Addition Operator

The addition operator in Octave is plus (+). The + operator is a binary operator. It requires two operands for the computation. The operands can be scalars or matrices.

Examples

Adding scalar operands

If the operands are scalars the addition operator adds the operands. Here in this example, x and y are scalar operands. We use the + operator to add and store the result in a variable called result.

>> x = 7;
>> y = 9;
>> result = x + y;
>> result

result = 16

Adding matrices

If the operands are matrices, the number of rows and columns of the operands must agree or must be broadcastable.

We can use the  .+  operator for the element-wise addition of the matrices.

>> x = [ 1 2 ; 3 4];

>> y = [ 5 6 ; 7 8];

>> result = x .+ y ;

>> result 

result = 

             6         8

            10      12
