红宝石 |矩阵划分/方法
/是 Ruby 中的一个内置方法,它返回一个矩阵,该矩阵由两个矩阵 mat1 和 mat2 相除。在这里,除法意味着乘以逆。
Syntax: mat1 / mat2
Parameters: The function need two matrix mat1 and mat2 which are to be divided.
Return Value: It returns the resultant matrix after divided.
示例 1 :
Ruby
# Ruby program for / method in Matrix
# Include matrix
require "matrix"
# Initialize a matrix
mat1 = Matrix[[1, 2, 6], [3, 4, 8], [12, 1, 3]]
mat2 = Matrix[[1, 2, 6], [3, 4, 8], [12, 1, 3]]
# Prints the value of mat1/mat2
puts mat1 / mat2
Ruby
# Ruby program for / method in Matrix
# Include matrix
require "matrix"
# Initialize a matrix
mat1 = Matrix[[1, 21], [31, 18]]
mat2 = Matrix[[1, 16], [31, 28]]
# Prints the value of mat1/mat2
puts mat1 / mat2
输出:
Matrix[[1/1, 0/1, 0/1], [0/1, 1/1, 0/1], [0/1, 0/1, 1/1]]

mat1 = Matrix[[1, 21], [31, 18]]
mat2 = Matrix[[1, 16], [31, 28]]
# Prints the value of mat1/mat2
puts mat1 / mat2
输出:
Matrix[[623/468, -5/468], [-155/234, 239/234]]
