# Ruby | Matrix rectangular() function

• Last Updated : 07 Jan, 2020

The rectangular() is an inbuilt method in Ruby returns two matrix. The first matrix returned has all the real values of the matrix, and the second matrix has all the imaginary values in the matrix.

Syntax: mat1.rectangular()

Parameters: The function needs the matrix whose real and imaginary values are to be returned.

Return Value: It returns two matrices which has real and imaginary values.

Example 1:

 `#Ruby program for rectangular() method in Matrix`` ` `#Include matrix``require ``"matrix"`` ` `#Initialize a matrix``    ``mat1``    ``= Matrix[[ 1, 21 ], [ 31, 18 ]]`` ` `#Prints two matrix with real``#and imaginary values``      ``puts` `mat1.rectangular()`

Output:

```Matrix[[1, 21], [31, 18]]
Matrix[[0, 0], [0, 0]]
```

Example 2:

 `#Ruby program for rectangular() method in Matrix`` ` `#Include matrix``require ``"matrix"`` ` `#Initialize a matrix``    ``mat1``    ``= Matrix[[ 1, 21 ], [ 31, 18 ], [ Complex(1, 9), 1 ]]`` ` `#Prints two matrix with real``#and imaginary values``      ``puts` `mat1.rectangular()`

Output:

```Matrix[[1, 21], [31, 18], [1, 1]]
Matrix[[0, 0], [0, 0], [9, 0]]```
