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” (10[1])(“O-D-E-four-five”) solver, (10[1])which can be sped up for large use-cases with this language’s built-in Parallel Computing Toolbox. (10[1])GNU Octave is a free, open-source alternative (10[2])to this language, which uses a semicolon to suppress output. Executable (10[1])code can be combined with formatted text and images in this language’s (-5[1])“live script” mode. A graphical environment used for controller modeling within this language is called Simulink. For 10 points, MathWorks develops what (10[1])engineering (10[1])programming language, (10[1])which is used for its ease of manipulating matrices? ■END■ (10[2])
