The first MATLAB sale was the following year, when Nick Trefethen from the Massachusetts Institute of Technology bought ten copies. 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. % Call subfoo1 twice, first giving a function name, then a function A subfunctionĭisp('You gave me a function handle.MATLAB (an abbreviation of "MATrix LABoratory" ) is a proprietary multi-paradigm programming language and numeric computing environment developed by MathWorks. Several features relating to function handles are demonstrated If you put this in a file called foo.m and run foo, If you need to perform string operations, such as string comparison or display, on a function handle, you can use func2str to obtain the function name in string format. It returns in a structure the function name, type, filename, and all of the methods for the function that were in scope at the time the function handle was created. The functions command returns information about a function handle that might be useful for debugging. The syntax for using this command isįeval(fhandle, arg1, arg2. The MATLAB feval command has to be used to run the function in aįunction handle. Your MATLAB environment - changing the PATH or adding otherįunctions with the same name as the original won't make a difference. Once you create a function handle, it is not affected by subsequent changes to That the " fun" routine that would be called from your own code Pass the name 'fun' you pass This ensures This is a situation where 'function handles' are useful. (see Finding Matlab functions for details). Ode23, ode23 might not use the " fun.m" file you expect - for example, the ode23 function may haveĪ sub-function or private function called " fun" The context of a function call affects which function isĪctually called - if you pass the function name " fun" to You need to pass the name of a function as an argument to another function. Sometimes (for instance when using the ODE function ode23)
