Last Updated : 07 Jan, 2020

The column_count() is an inbuilt method in Ruby returns the number of columns in a matrix.

Syntax: mat1.column_count() Parameters: The function does not accepts any parameter. Return Value: It returns the number of columns in a matrix.

Example 1:

Ruby

# Ruby program for column_count() method in Matrix

# Include matrix 
require "matrix"

# Initialize a matrix 
mat1 =  Matrix[[1, 21], [31, 18]]    

# prints the number of columns 
puts  mat1.column_count

Output:

Example 2:

Ruby

# Ruby program for column_count() method in Matrix

# Include matrix 
require "matrix"

# Initialize a matrix 
mat1 =  Matrix[[13, 1, 5], [12, 1, 5], [11, 2, 5]]   

# prints the number of columns 
puts  mat1.column_count
