![]() was founded to develop the software and the MATLAB programming language was released. MATLAB was first released as a commercial product in 1984 at the Automatic Control Conference in Las Vegas. John Little and programmer Steve Bangert re-programmed MATLAB in C, created the MATLAB programming language, and developed features for toolboxes. They decided to reprogram MATLAB in C and market it for the IBM desktops that were replacing mainframe computers at the time. ![]() Moler would leave copies at universities he visited and the software developed a strong following in the math departments of university campuses. At the time, MATLAB was distributed for free to universities. Early versions of MATLAB were simple matrix calculators with 71 pre-built functions. The software was disclosed to the public for the first time in February 1979 at the Naval Postgraduate School in California. The first early version of MATLAB was completed in the late 1970s. There were no programs, no toolboxes, no graphics. In the beginning (before version 1.0) MATLAB "was not a programming language it was a simple interactive matrix calculator. This was followed by Fortran code for linear equations in 1971. He developed MATLAB's initial linear algebra programming in 1967 with his one-time thesis advisor, George Forsythe. Moler became a math professor at the University of New Mexico and started developing MATLAB for his students as a hobby. The idea for MATLAB was based on his 1960s PhD thesis. ![]() MATLAB was invented by mathematician and computer programmer Cleve Moler. As of 2017, more than 5000 global colleges and universities use MATLAB to support instruction and research. They come from various backgrounds of engineering, science, and economics. An additional package, Simulink, adds graphical multi-domain simulation and model-based design for dynamic and embedded systems.Īs of 2020, MATLAB has more than 4 million users worldwide. MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages.Īlthough MATLAB is intended primarily for numeric computing, an optional toolbox uses the MuPAD symbolic engine allowing access to symbolic computing abilities. On the PC, adding & to the end of the ! command line, as in !dir &, causes the output to appear in a separate window.MATLAB (an abbreviation of "MATrix LABoratory" ) is a proprietary multi-paradigm programming language and numeric computing environment developed by MathWorks. Indicates that the rest of the input line is issued as a command to the operating system. MATLAB displays the first contiguous comment lines in a M-file in response to a help command.Įxclamation point. The percent symbol denotes a comment it indicates a logical end of line. Used after an expression or statement to suppress printing or to separate statements. For multi-statement lines, the comma can be replaced by a semicolon to suppress printing. Used to separate statements in multistatement lines. Used to separate matrix subscripts and function arguments. Three or more points at the end of a line indicate continuation.Ĭomma. A.(field) and A(i).field, when A is a structure, access the contents of field.Ĭontinuation. See the Arithmetic Operators page.įield access. 314e1 are all the same.Įlement-by-element operations. A quotation mark within the text is indicated by two quotation marks.ĭecimal point. 'any text' is a vector whose components are t he ASCII codes for the characters. X' is the complex conjugate transpose of X. For example, A(,:) = A(,:) interchanges rows 1 and 5 of A. If V has m components and W has n components, then A(V,W) is the m-by- n matrix formed from the elements of A whose subscripts are the elements of V and W. The same indirect subscripting works in matrices. If X has n components, X(n:- 1:1) reverses them. See help paren for more information about ( ). An error occurs if any such subscript is less than 1 or greater than the size of X. The components of V must be integers to be used as subscripts. They are also used to enclose subscripts of vectors and matrices in a manner somewhat more general than usual. They are used to enclose arguments of functions in the usual way. ![]() Parentheses are used to indicate precedence in arithmetic expressions in the usual way.
