Question

10) you will run/call the function with these given values. (b) Write a flow chart and the script file using conditional statements with logical operator if/else and if/elseif, to evaluate the following function, assuming that the scalar x has a value: y 2 sin(m) for-1 x < 5 y=10(X-5) + 1 for x 25 Use your file to evaluate y for x5,x 3 and x 15 by hand

Answer 1

MATLAB Script File:

close all
clear
clc

fprintf('y(x = -5) = %f\n', func(-5))
fprintf('y(x = 3) = %f\n', func(3))
fprintf('y(x = 15) = %f\n', func(15))

function y = func(x)
if x < -1
y = exp(-x+1);
else
if x >= -1 && x < 5
y = 2*sin(pi*x);
else
if x >= 5
y = 10*(x-5)+1;
end
end
end
end

Output:

y(x = -5) = 403.428793
y(x = 3) = 0.000000
y(x = 15) = 101.000000
