The unitary?() is an inbuilt method in Ruby returns a boolean value. It returns true if it is a unitary matrix, else it returns false. It returns error if anything other than unitary matrix is used.
Syntax: mat1.unitary?()
Parameters: The function needs the matrix to be checked for unitary matrix or not.
Return Value: It returns true if it is a unitary matrix, else it returns false.
Example 1:
# Ruby program for unitary?() method in Matrix # Include matrix require "matrix"
# Initialize a matrix mat1 = Matrix[[1, 0], [0, Complex(0,1)]]
# Prints if unitary? or not puts mat1.unitary?() |
Output:
true
Example 2:
# Ruby program for unitary?() method in Matrix # Include matrix require "matrix"
# Initialize a matrix mat1 = Matrix[[0, -6, 4], [-6, 0, 7], [4, 7, 0]]
# Prints if unitary? or not puts mat1.unitary?() |
Output:
false
