MATLAB - Wikipedia. MATLAB (matrix laboratory) is a multi- paradigmnumerical computing environment and fourth- generation programming language. Cleve Moler, the chairman of the computer science department at the University of New Mexico, started developing MATLAB in the late 1970s. A proprietary programming language developed by Math. Works, MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, C#, Java, Fortran and Python. Although MATLAB is intended primarily for numerical computing, an optional toolbox uses the Mu. PADsymbolic engine, allowing access to symbolic computing abilities. An additional package, Simulink, adds graphical multi- domain simulation and model- based design for dynamic and embedded systems. In 2. 00. 4, MATLAB had around one million users across industry and academia. It soon spread to other universities and found a strong audience within the applied mathematics community. Jack Little, an engineer, was exposed to it during a visit Moler made to Stanford University in 1. Recognizing its commercial potential, he joined with Moler and Steve Bangert. For comments, bug reports, encouragement, suggestions, complaints, etc., please send email to: [email protected]. If you use SOSTOOLS for research. Symbolic Math Toolbox. You can create, run, and share symbolic math code using. They rewrote MATLAB in C and founded Math. Works in 1. 98. 4 to continue its development. These rewritten libraries were known as JACKPAC. It is now also used in education, in particular the teaching of linear algebra, numerical analysis, and is popular amongst scientists involved in image processing. Common usage of the MATLAB application involves using the Command Window as an interactive mathematical shell or executing text files containing MATLAB code.
MATLAB is a weakly typed programming language because types are implicitly converted. Values can come from constants, from computation involving values of other variables, or from the output of a function. For example: > > x=1. For instance: defines a variable named array (or assigns a new value to an existing variable with the name array) which is an array consisting of the values 1, 3, 5, 7, and 9. That is, the array starts at 1 (the init value), increments with each step from the previous value by 2 (the increment value), and stops once it reaches (or to avoid exceeding) 9 (the terminator value). Indexing is one- based. The list of elements should be surrounded by square brackets: . Parentheses: () are used to access elements and subarrays (they are also used to denote a function argument list).> > A=. For example, a submatrix taken from rows 2 through 4 and columns 3 through 4 can be written as: > > A(2: 4,3: 4)ans=1. A square identity matrix of size n can be generated using the function eye, and matrices of any size with zeros or ones can be generated with the functions zeros and ones, respectively.> > eye(3,3)ans=1. Most MATLAB functions can accept matrices and will apply themselves to each element. For example, mod(2*J,n) will multiply every element in . MATLAB does include standard . This code, excerpted from the function magic. M for odd values of n (MATLAB function meshgrid is used here to generate square matrices I and J containing 1: n). In addition, MATLAB supports dynamic field names. Unfortunately, MATLAB JIT does not support MATLAB structures, therefore just a simple bundling of various variables into a structure will come at a cost. Valid function names begin with an alphabetic character, and can contain letters, numbers, or underscores. Functions are also often case sensitive. Function handles. MATLAB has value classes and reference classes, depending on whether the class has handle as a super- class (for reference classes) or not (for value classes). For example, a call to a methodcan alter any member of object only if object is an instance of a reference class. An example of a simple class is provided below. Hello!')endendend. When put into a file named hello. Hello! Graphics and graphical user interface programming. MATLAB includes GUIDE. For example, the function plot can be used to produce a graph from two vectors x and y. The code: x=0: pi/1. A MATLAB program can produce three- dimensional graphics using the functions surf, plot. In MATLAB, graphical user interfaces can be programmed with the GUI design environment (GUIDE) tool. The dynamically loadable object files created by compiling such functions are termed . Calling MATLAB from Java is more complicated, but can be done with a MATLAB toolbox. Official MATLAB API for Java was added in 2. If an evaluation license is requested, the Math. Works sales department requires detailed information about the project for which MATLAB is to be evaluated. If granted (which it often is), the evaluation license is valid for two to four weeks. A student version of MATLAB is available as is a home- use license for MATLAB, Simulink, and a subset of Mathwork's Toolboxes at substantially reduced prices. It has been reported that European Union (EU) competition regulators are investigating whether Math. Works refused to sell licenses to a competitor. There are also freeopen source alternatives to MATLAB, in particular GNU Octave, Scilab, Free. Mat, Julia, and Sage. Math which are intended to be mostly compatible with the MATLAB language. Among other languages that treat arrays as basic entities (array programming languages) are APL, Fortran 9. S- Lang, as well as the statistical languages R and S. There are also libraries to add similar functionality to existing languages, such as IT++ for C++, Perl Data Language for Perl, ILNumerics for . NET, Num. Py/Sci. Py/matplotlib for Python, Sci. Lua/Torch for Lua, Sci. Ruby for Ruby, and Numeric. Java. Script. GNU Octave is unique from other alternatives because it treats incompatibility with MATLAB as a bug (see MATLAB Compatibility of GNU Octave). Therefore, GNU Octave attempts to provide a software clone of MATLAB. Release history. For example, typing in . Other commands include . Not every Easter egg appears in every version of MATLAB.
