•           Analisa Numerik

•           Tutorial Matlab

•             Ref : http://www.rit.edu/~pnveme/Matlab_Course

•           Pendahuluan

•            MATLAB (Matrix Laboratory)

–       High performance language for technical computing.

–       Interactive system yg. basic data element-nya adlh. array yg. tidak membutuhkan dimensioning.

–       Terdiri atas 6 bagian :

•        Bhs. pemrograman MATLAB.

      High-level matrix/array language dng. features control flow statements, functions, data structures, input/output, and object-oriented programming. Aplikasi MATLAB ditulis dlm. M-files.

•        MATLAB working environment.

      Set of tools and fasilitas yg. digunakan oleh MATLAB user / programmer. Meliputi fasilitas utk. me-manage variables, import & export data, tools utk. developing, managing, debugging, & profiling M-files, MATLAB's applications.    

•           Pendahuluan

•        Grafik.

      Termasuk 2-D & 3-D data visualization, image processing, animation, & presentation graphics, low-level commands utk. GUI aplikasi MATLAB.

•        MATLAB mathematical function library.

      Computational algorithms : dari fungsi-fungsi dasar (sum, sin, cos), complex arithmetic, sampai fungsi-fungsi yg. lebih komplesk (matrix inverse, matrix eigenvalues, Bessel functions, & fast Fourier transforms).    

•        MATLAB Application Program Interface (API).

      A library yg. memungkinkan kita menulis program C & Fortran programs yg. dpt. berinteraksi dng. MATLAB.  Meliputi fasilitas utk. calling routines dr. MATLAB (dynamic linking), calling MATLAB as a computational engine, membaca, & menulis MAT-files.    

•        Toolboxes

      Extension dari basic Matlab system (penambahan additional mathematical function library pd. topik-topik tertentu).

•           Variables

•            Tidak perlu didefinisikan terlebih dahulu sebelum dipakai. Default : semua bertipe matrix.

•            Nama variabel case sensitive, diawali dng. 1 huruf & bisa sampai 31 chars (huruf, bil., underscore).

•            Ada built-in variabel.

•            Operator :

+, -, *, /, \ (x = A^-1b), ^, ‘ (transpose), (), .[ops]

•            Semua komputasi di MATLAB dilakukan sebg. double precision (IEEE standard), sekitar 16 digit. Penampilan bisa berbeda-beda, tergantung format.

•           Functions

•           Fungsi di MATLAB :

–      Built-in function, yg. umum digunakan bisa dikelompokkan menjadi 3 :

•       Elementary buil-in functions (elfun).

•       Special Math functions (specfun, elmat).

•       Toolboxes

–      User defined function : M-files

•       Program Matlab umumnya terdiri atas 1/beberapa function (dlm. M-files).

•           User Defined Functions

•            % : Comment

        Comment di awal function (sebelum dipisah baris kosong) otomatis jadi help.

•            Program control :

–       if - else - end.

–       switch - case - … - end.

–       for - … - end.

–       while - … - end.

–       break.

•            Selain fungsi flops, cputime, dsb., MATLAB juga menyediakan profiler (profile, profile report).
