PLOTS WITH RECTANGLE
>>Rectangle('Position',[x,y,w,h])
Draws the rectangle from the point x,y and having a width of
w and a height of h. Specify values in axes data units.
>> rectangle('Position',[0.2,0.5,5,7])
PLOTS WITH LOGARITHMIC AXES
Many science and engineering applications require plots in which one or both axes have a logarithmic(log) scale.log scales provide means for representing data over a wide range of values
semilogy(x,y) - Ploats y versus x with a log (base 10) scale for y axis and linear scale for the x axis
semilogx(x,y) - Ploats y versus x with a log (base 10) scale for x axis and linear scale for the y axis
loglog(x,y) - Ploats y versus x with a log (base 10) scale for the both axis
Q):-plot of the function y=2.^(-0.2x+10)
>> x=linspace(0.1,60,1000);
>> y=2.^(0.2*x+10);
>> plot(x,y)
>> x=linspace(0.1,60,1000);
>> y=2.^(0.2*x+10);
>> semilogx(x,y)
>> x=linspace(0.1,60,1000);
>> y=2.^(0.2*x+10);
>> semilogy(x,y)
>> x=linspace(0.1,60,1000);
>> y=2.^(0.2*x+10);
>> loglog(x,y)
