1. Here's a MATLAB script, explains it line by line in details.
>> x = 0:pi/100:2*pi;
>> y1 = 2*cos(x);
>> y2 = cos(x);
>> y3 = 0.5*cos(x);
>>
plot(x,y1,'--',x,y2,'-',x,y3,':')
>> xlabel('0 \leq x\leq 2\pi')
>>ylabel('Cosine functions')
>> legend('2*cos(x)','cos(x)','0.5*cos(x)')
>> title('Typical example of multiple plots')
>> axis([0 2*pi -3 3])
