Hi, I am facing difficulty in plotting these functions.

k=1;
x=[0:0.5:24];
y1= k*sin(pi*(x-12.9677)/14.8646);
y1(y1 < 0) = 0;
y2= k*sin(pi*(x-16.0495)/12.7009);
y2(y2 < 0) = 0;
y=y1+y2;
plot(x,y1);
hold on
plot(x,y2);
I want to plot y1 and y2 such that after 24 at the x coordinate, y1 and y2 arrive from 0 at x coordinate and the value of y1 at 24 , i.e. y1(24) = y1(0) and the the y curve must follow its original course as it would have followed after 24 but from 0 till the termination on the x-axis.
Here, based on my code (wrong), y1 is not showing up again from 0 till termination point and y2 is showing up but starting at a lower value from 0.
Also please keep in mind that i further wan sum of y1 and y2 in the 0 to 24 range.
0 to 24 is the time of day.
Thanks for reading. we

I'd try out to expand x axis by 'axis' command to make the figure's axis bigger than your plot's width.

In that case you're going to need to change your y1 function. y1(0) will be equal (approximately) at x = 2*14.8646.
>> k = 1;
>> y1 = @(x) k*sin(pi*(x-12.9677)/14.8646);
>> y1([0 24])
ans =
-0.3903 0.7243
>> y1([0 2*14.8646])
ans =
-0.3903 -0.3903
Similarly for y2, with x = 2*12.7009:
>> k = 1;
>> y2 = @(x) k*sin(pi*(x-16.0495)/12.7009);
>> y2([0 24])
ans =
0.7368 0.9227
>> y2([0 2*12.7009])
ans =
0.7368 0.7368
