红宝石 |矩阵正则?()函数
常规?()是 Ruby 中的一个内置方法,它返回一个布尔值。如果是正则矩阵则返回真,否则返回假。
Syntax: mat1.regular?()
Parameters: The function needs the matrix to be checked for regular matrix or not.
Return Value: It returns true if it is a regular matrix, else it returns false.
示例 1 :
# Ruby program for regular?() method in Matrix
# Include matrix
require "matrix"
# Initialize a matrix
mat1 = Matrix[[1, 21], [31, 18]]
# Prints if regular? or not
puts mat1.regular?()
输出:
true
示例 2 :
# Ruby program for regular?() method in Matrix
# Include matrix
require "matrix"
# Initialize a matrix
mat1 = Matrix[[0, 0], [0, 0]]
# Prints if regular or not
puts mat1.regular?()
输出:
false
