  2. Bibliografia • Hahn, B., Valentine, D., Essential Matlab for Engineers and Scientists, 4th Ed., Oxford: Academic Press, 2010. • Gilat, A., Matlab: An Introduction with Applications, John Wiley & Sons, 2004. • Cagy, M., Fundamentos de Matlab, apostila, 2013. • Castilho, M., Gomes, E., Gonçalves Jr., J.I., Santos, L.A., Kultz, R., Krynski, E.M., Guia Rápido de Referência da Linguagem Pascal - Versão Free Pascal, apostila, 2009. • Graves, D., Pascal Programming Guide, Silicon Graphics, Inc., 1993.

  3. Linguagens Interpretadas vs. Compiladas Interpretadas: Código fonte (script) depende de um programa (interpretador) para serem executadas; Multi-plataformas. Compiladas: O código final (gerado pelo compilador) é executável diretamente pelo Sistema Operacional; Depende da arquitetura da máquina e do SO.

  4. Linguagens Interpretadas de Aplicações Genéricas ASP BASIC C# CYBOL DMDScript Euphoria Java JavaScript Lisp Logo • PHP • Python • R • Ruby • S • VBScript • VisualAge • VisualWorks • Tcl

  5. Linguagens Interpretadas Orientadas a Matrizes • SciLab; • Octave; • FreeMat; • JMathLib; • Matlab.

  6. Linguagens Compiladas Ada ALGOL BASIC C C++ COBOL Delphi Eiffel Fortran • Pascal • Sather • Ubercode • Urq • Visual Basic • Visual Foxpro • Visual Prolog
