Ruby 矩阵 +方法
在Ruby中, + 是一个内置的方法,它返回一个矩阵,该矩阵是两个矩阵mat1和mat2的相加。
语法 :mat1 + mat2
参数 :该函数需要两个矩阵mat1和mat2相加。
返回值 :它返回加法后的结果矩阵。
例子 1 :
# 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
输出:
Matrix[[2, 4, 12], [6, 8, 16], [24, 2, 6]]
例2 :
# Ruby program for + method in Matrix
# Include matrix
require "matrix"
# Initialize a matrix
mat1 = Matrix[[1, 21, 6], [31,124, 18]]
mat2 = Matrix[[1, 12, 16], [31, 43, 28]]
# Prints the value of mat1+mat2
puts mat1 + mat2
输出:
Matrix[[2, 33, 22], [62, 167, 46]]
