This programming language includes easter eggs such as producing a dog’s face when running the function “spy” with no argument. Fourth- and fifth-order methods are compared using this language’s built-in “ode45” (“O-D-E-four-five”) solver, which can be sped up for large use-cases with this language’s built-in Parallel Computing Toolbox. GNU Octave is a free, open-source alternative to this language, (10[1])which uses a semicolon to suppress output. Executable code can be combined (10[1])with formatted text and images in this language’s “live script” mode. A graphical (-5[1])environment used for controller modeling within this language is called Simulink. For 10 points, MathWorks develops what engineering programming language, which is used for its ease of manipulating (10[2])matrices? ■END■ (10[4]0[2])
