Задание 1

Создать функцию пользователя y=sinh(x)+sin(x)-1 вычислить значения в точке x0=3,1 и построить график функции в интервале [-2;5] с шагом 0,1.

Решение:

Представим данную функцию в m=file (рис.1).

Рис.1 «Функция m-file»

Далее переходим в Matlab (Command Window)

>> z=haf(3.1)

z = 10.11803170195733

>> x=-2:0.1:5;

>> y=sinh(x)+sin(x)-1;

>> plot(x,y,['r','*','-.'])

>> grid on

Рис.2 «График заданной функции»

Вывод: Создали функцию пользователя, вычислили значение функции в точке x0=3,1, где у=10.118. Построили график функции при заданных интервалах (рис.2).
