Ruby | Matrix rank() function

Last Updated : 07 Jan, 2020

The rank() is an inbuilt method in Ruby returns the rank of the given matrix. The float values can yield enormous results due to float precision

Syntax: mat1.rank()

Parameters: The function does not accepts any parameter.

Return Value: It returns the rank of the current matrix.

Example 1:

#Ruby program for rank() method in Matrix 
  
#Include matrix 
require "matrix"
  
#Initialize a matrix 
    mat1 
    = Matrix[[ 1, 21 ], [ 31, 18 ]] 
  
#Prints the rank 
      puts mat1.rank() 

Output:

Example 2:

#Ruby program for rank() method in Matrix 
  
#Include matrix 
require "matrix"
  
#Initialize a matrix 
    mat1 
    = Matrix[[ 1, 0 ], [ 0, 1 ]] 
  
#Prints the rank 
      puts mat1.rank() 

Output:
