Example 2 Matlab % MATLAB Code to illustrate %input age = input('how old are you: '); % At this point, the variable: age, will contain % whatever value the user types Output: 20 Vector, Matrix, and Array CommandsCommand Usecat Concatenates the arrayfindFinds the indices of nonzero elementsmax Returns the largest elementminReturns the smallest elementprodProduct of each columnsortSorts each columnrankComputes rank of a matrixeyeCreates an identity matrixinv Computes the inverse of a matrix Example 1 Matlab % MATLAB Code to illustrate %cat array1 = [1,2,3] array2 = [4,5,6] cat(1,array1,array2) Output: ans = 1 2 3 4 5 6 Example 2 Matlab % MATLAB Code to illustrate %max max(array1) Output: ans = 3 Example 3 Matlab %MATLAB Code to illustrate %min min(array2) Output: ans = 4 Matlab %MATLAB Code to illustrate %eye eye(2,2) Output: ans = Diagonal Matrix 1 0 0 1 Plotting Commands: Commands UseaxisSets axis limitgridDisplays grid linesplotGenerates xy plottitle Puts title at top of the plotclose Closes current plotbarCreates bar chartprint Prints the plot / saves the plotfigureOpens a new figure windowClose allCloses all plots Example1: Matlab % MATLAB Code to illustrate %plot x = linspace(0,20) y = cos(x) plot(x,y) Output: Example 2: Matlab %MATLAB Code to illustrate %grid x = linspace(0,20) y = cos(x) plot(x,y) grid on Output: Comment More infoAdvertise with us Next Article MATLAB Commands deepthikamath Follow Improve Article Tags : Software Engineering MATLAB Similar Reads Comments in MATLAB Comments are generic English sentences, mostly written in a program to explain what it does or what a piece of code is supposed to do. More specifically, information that programmer should be concerned with and it has nothing to do with the logic of the code. They are completely ignored by the compi 2 min read What is a Command? A command typically refers to an order given to a computer program or operating system to perform a specific task. It's usually entered via a command line interface or a terminal. Commands can vary widely depending on the context, the operating system being used, and the specific program or utility 5 min read MATLAB - Loops MATLAB stands for Matrix Laboratory. It is a high-performance language that is used for technical computing. It was developed by Cleve Molar of the company MathWorks.Inc in the year 1984.It is written in C, C++, Java. It allows matrix manipulations, plotting of functions, implementation of algorithm 2 min read Functions in MATLAB Methods are also popularly known as functions. The main aim of the methods is to reuse the code. A method is a block of code which is invoked and executed when it is called by the user. It contains local workspace and independent of base workspace which belongs to command prompt. Let's take a glance 5 min read Factorial in MATLAB MATLAB is a high-performance language that is used for matrix manipulation, performing technical computations, graph plottings, etc. It stands for Matrix Laboratory. In this article, we'll be calculating the factorial of a number n using MATLAB's built-in function 'factorial(number)'. Factorial:The 1 min read What is a Command Prompt? We need tools to interact with the operating system of the computer. This is where Graphical User Interface and Command Prompts come into play. Graphical User Interface allows users to interact with the Operating System for simple tasks. Command Prompts are used for complicated tasks like batch proc 4 min read R Program Commands R is a powerful programming language and environment designed for statistical computing and data analysis. It is widely used by statisticians, data scientists, and researchers for its extensive capabilities in handling data, performing statistical analysis, and creating visualizations.
