Matlab graph plotting example1

1st of all, I am not the person who wrote the code; I found the code in one china forum.

In my point of view, the code is simple and very useful for the beginner who just starting at matlab programming.

The above example is generating a sine wave using the matlab m-file.

below is the code,

function shili01
h0=figure('toolbar','none',...
'position',[198 56 350 300],...
'name','example1');
x=-pi:0.05:pi;
y=sin(x);
plot(x,y);
xlabel('X');
ylabel('Y');
title('SIN( )');
grid on

here is the explanation, the above code is runnable, just copy to m-file, save it, and run it.


function shili01 % this indicate the function's name is shili01
h0=figure('toolbar','none',... % figure is to open above window
'position',[198 56 350 300],...%position is the figure size [left, bottom, width, height]

%(195=left, 56=bottom, 350=width, 300 =height)
'name','example1');%giving the figure a name=example 1
x=-pi:0.05:pi; %x=-3.14159265, then adding -3.14159265+0.05, continue the adding until %x=3.14159265
y=sin(x);%mathematical function of sine
plot(x,y);%plotting the graph
xlabel('X');%labeling X the graph at x axis; you can change the name 'X' to anything you like
ylabel('Y');%labeling Y the graph at y axis; you can change the name 'Y' to anything you like
title('SIN( )');%title of the graph, that is SIN()
grid on%you can try change grid on to grid off to see the different

I also a beginner in matlab,
so please tell me if my explanation is wrong.
