Syntax: mat1 - mat2 Parameters: The function need two matrix mat1 and mat2 which are to be subtracted. Return Value: It returns the resultant matrix after subtraction. Example 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 Output: Matrix[[0, 0, 0], [0, 0, 0], [0, 0, 0]] Example 2: Ruby # 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 Output: Matrix[[0, 9, -10], [0, 81, -10]] Create Quiz Comment G gopaldave Follow 0 Improve G gopaldave Follow 0 Improve Article Tags : Ruby Ruby-Methods Ruby Matrix-class Explore OverviewRuby For Beginners3 min readRuby Programming Language (Introduction)4 min readComparison of Java with Other Programming Languages4 min readSimilarities and Differences between Ruby and C language3 min readSimilarities and Differences between Ruby and C++3 min readEnvironment Setup in Ruby3 min readHow to install Ruby on Linux?2 min readHow to install Ruby on Windows?2 min readInteresting facts about Ruby Programming Language2 min readBasicsRuby | Keywords4 min readRuby | Data Types3 min readRuby Basic Syntax3 min readHello World in Ruby2 min readRuby | Types of Variables4 min readGlobal Variable in Ruby2 min readComments in Ruby2 min readRuby | Ranges4 min readRuby Literals4 min readRuby Directories5 min readRuby | Operators11 min readOperator Precedence in Ruby2 min readOperator Overloading in Ruby5 min readRuby | Pre-define Variables & Constants5 min readRuby | unless Statement and unless Modifier2 min readControl StatementsRuby | Decision Making (if, if-else, if-else-if, ternary) | Set - 13 min readRuby | Loops (for, while, do..while, until)5 min readRuby | Case Statement3 min readRuby | Control Flow Alteration7 min readRuby Break and Next Statement2 min readRuby redo and retry Statement2 min readBEGIN and END Blocks In Ruby2 min readFile Handling in Ruby4 min readMethodsRuby | Methods3 min readMethod Visibility in Ruby3 min readRecursion in Ruby4 min readRuby Hook Methods5 min readRuby | Range Class Methods5 min readThe Initialize Method in Ruby2 min readRuby | Method overriding2 min readRuby Date and Time3 min readOOP ConceptsObject-Oriented Programming in Ruby | Set 19 min readObject Oriented Programming in Ruby | Set-28 min readRuby | Class & Object4 min readPrivate Classes in Ruby3 min readFreezing Objects | Ruby2 min readRuby | Inheritance4 min readPolymorphism in Ruby3 min readRuby | Constructors2 min readRuby | Access Control8 min readRuby | Encapsulation2 min readRuby Mixins3 min readInstance Variables in Ruby3 min readData Abstraction in Ruby3 min readRuby Static Members3 min readExceptionsRuby | Exceptions4 min readRuby | Exception handling6 min readCatch and Throw Exception In Ruby3 min readRaising Exceptions in Ruby4 min readRuby | Exception Handling in Threads | Set - 12 min readRuby | Exception Class and its Methods3 min readRuby RegexRuby | Regular Expressions3 min readRuby Search and Replace2 min readRuby ClassesRuby | Float Class7 min readRuby | Integer Class3 min readRuby | Symbol Class5 min readRuby | Struct Class5 min readRuby | Dir Class and its methods3 min readRuby | MatchData Class4 min readRuby ModuleRuby | Module4 min readRuby | Comparable Module3 min readRuby | Math Module4 min readInclude v/s Extend in Ruby2 min readCollectionsRuby | Arrays4 min readRuby | String Basics5 min readRuby | String Interpolation3 min readRuby | Hashes Basics4 min readRuby | Hash Class12 min readRuby | Blocks6 min read Like
