1. Write a Matlab function, piecewise (), that will calculate and return the value of the function f(x) defined by: 0

piecewise.m

function y=piecewise(x)
if(x<=0)
y=1;
elseif(x>0 && x<=3)
y=exp(-x);
elseif(x>3 && x<=5)
y=-cos(3*x);
elseif(x>5)
y=2*sin(x);
end
end

plotpiecewise.m

x=[];
for i=-3:0.01:8
x=[x,i];

y=[];
for i=-3:0.01:8
y=[y,piecewise(i)];
end
plot(x,y);
xlabel('x')
ylabel('y')
