Ruby 编程中的 Transpose() 函数

Ruby 语言中 transpose 函数主要用于返回数组或矩阵的转置。

语法

array.transpose

或

Matrix.transpose

我们先举几个数组中 transpose  函数的示例，然后再举几个矩阵中的示例。

示例 1

考虑以下所示代码

Open Compiler
# transpose() in array

# array declaration
first_arr = [[18, 22], [33, 3], [8, 6]]

# array declaration
second_arr = [[1, 3, 2, 5, 88, 9]]

# print statements
puts "transpose() output :
#{first_arr.transpose()}"

puts "transpose() output :
#{second_arr.transpose()}"

输出

transpose() output : [[18, 33, 8], [22, 3, 6]]
transpose() output : [[1], [3], [2], [5], [88], [9]]

示例 2

Open Compiler
# transpose() in array

# array declaration
first_arr = [["xyz", "nil", "cat"]]

# array declaration
second_arr = [["donkey", "go", "lion"]]

# print statements
puts "transpose() output :
#{first_arr.transpose()}"

puts "transpose() output :
#{second_arr.transpose()}"

输出

transpose() output : [["xyz"], ["nil"], ["cat"]]
transpose() output : [["donkey"], ["go"], ["lion"]]

现在让我们探讨几个矩阵上的转置示例。

示例 3

Open Compiler
# transpose() in Matrix

require "matrix"

# Initializing matrix
matOne = Matrix[[5, 11], [1, 9]]

# Prints the transpose matrix
puts matOne.transpose()

输出

Matrix[[5, 1], [11, 9]]

示例 4

Open Compiler
# transpose() in matrix

require "matrix"

# Initializing matrix
matOne = Matrix[[1, 2], [6, 3], [4, 2]]

# Printing matrix
puts matOne.transpose()

输出

Matrix[[1, 6, 4], [2, 3, 2]]
