What Is matlabe The MATLAB System The MATLAB system consists of five main parts Development Environment. This is the set of tools and facilities that help you use MATLAB functions and files. Many of these tools are graphical user interfaces It includes the matlab desktop and Command window, a command history n editor and debugger and browsers for viewing help the workspace, files and the search path The MATLAB Mathematical Function Library. This is a vast collection of computational algorithms ranging from elementary functions like sum, sine, cosine, and complex arithmetic, to more sophisticated functions like matrix inverse, matrix eigenvalues, Bessel functions, and fast Fourier transforms The MATLAB Language. This is a high-level matrix/array language with control flow statements, functions, data structures, input/output, and object-oriented programming features. It allows both"programming in the small "to rapidly create quick and dirty throw-away programs, and"programming in the large to create complete large and complex application programs Graphics. MATLAB has extensive facilities for displaying vectors and matrices as graphs, as well as annotating and printing these graphs. It includes high-level functions for two-dimensional and three-dimensional data visualization, image processing, animation, and presentation graphics. It also includes low-level functions that allow you to fully customize the appearance of graphics as well as to build complete graphical user interfaces on your MATLAB applications The MATLAB Application Program Interface (APl]. This is a library that allows you t write C and Fortran programs that interact with MATLAB. It includes facilities for calling routines from MatLAB (dynamic linking), calling MATLAB as a computational engine and for reading and writing Mat-files
