Пример ИКЗ

В файле ML1_13.txt собраны данные о требованиях к твердости различных деталей газовой арматуры. Каждая строка относится к одной из деталей и содержит 2 числа: наименьшее и наибольшее допустимое значение твердости стали для данной детали. Номер строки соответствует номеру, обозначающему деталь. Пользователь должен иметь возможность ввести номер детали и значения измеренной твердости и получить суждение о выполнении или невыполнении требований по твердости. Для уменьшения ошибки в суждениях измерения повторяются 5 раз. При решении задачи по введенным пользователем 5 измерениям твердости необходимо рассчитать среднее арифметическое значение измеренной твердости. Если это среднее окажется между наименьшим и наибольшим допустимыми значениями для данной детали, то выдается суждение «Требования по твердости выполнены», в ином случае – суждение «Требования по твердости не выполнены».

1 способ решения: через командное окно (программа T8_1.m):

Matr=load('ML1_13.txt') while 1

prov=1

while prov==1 n=input('Номер детали: ')

if n<=size(Matr,1) prov=0

else

disp('Детали не обнаружено!') end

end

for i=1:5

d(i)=input(['Измеренное значение твердости № ' num2str(i) ' = '])

end srednee=sum(d)/5

if (Matr(n,1)<=srednee) & (Matr(n,2)>=srednee) k=1

disp('Требования по твердости выполнены') else

k=0

disp('Требования по твердости не выполнены') end

pr=input('Введите 1 для вывода результатов в print1.txt, иначе введите любое другое число: ')

if pr==1 fp=fopen('print1.txt','w')

fprintf(fp,'Деталь № %2.0d \n',n)

fprintf(fp,'Граничные значения твердости от %3.0d до %3.0d \n',Matr(n,1),Matr(n,2))

fprintf(fp,['Измеренные значения: ' num2str(d)]) if k==1

fprintf(fp,'\nСуждение: Требования по твердости выполнены') else

fprintf(fp,'\nСуждение: Требования по твердости не выполнены')

end fclose(fp)

end

cntn=input('Введите 1 для продолжения расчетов, иначе введите любое другое число: ')

if cntn~=1 break

end end

2 способ решения: с помощью экранной формы.

1. Главная программа T8_2.m global Matr Nomer Matr=load('ML1_13.txt') Nomer=size(Matr,1) run('detaly.m

2. Экранная форма detaly.fig:

3. Программа detaly.m, обслуживающая экранную форму (файл создается автоматически при создании формы; добавленный код выделен желтым):

function varargout = detaly(varargin)

%DETALY MATLAB code for detaly.fig

%DETALY, by itself, creates a new DETALY or raises the existing

%singleton*.

%

%H = DETALY returns the handle to a new DETALY or the handle to

%the existing singleton*.

%

%DETALY('CALLBACK',hObject,eventData,handles,...) calls the local

%function named CALLBACK in DETALY.M with the given input

arguments.

%DETALY('Property','Value',...) creates a new DETALY or raises the

%existing singleton*. Starting from the left, property value

pairs are

%applied to the GUI before detaly_OpeningFcn gets called. An

%unrecognized property name or invalid value makes property

application

%stop. All inputs are passed to detaly_OpeningFcn via varargin.

%*See GUI Options on GUIDE's Tools menu. Choose "GUI allows only

one

%instance to run (singleton)".
