The assigned task is to make a triangular function with peak amplitude of 1 over -5 to +5 without any inbuilt functions.
My approach was to use the respective line equation for x>0 and x<0, but I didn't kow how to do it.
Any other approach to this problem is also appreciated.
Edit:- for some clarity, we are not supposed to use functoins like "Saw-tooth" in this case. while functions like ones,zeroes,plot are fine
The following is my code for the approach I have mentioned above, Any othe approaches are also welcomed
And does anyone know why the title,xlabel,ylabel are not being showed in the output?'
Thanks!
x = (0: 1:5);
k = (-5 :1 :0);
grid on;
g = (k/5) + 1;
y =(-x/5) + 1;
title('Task-2 Triangular Signal');
xlabel('Time');
ylabel('Amplitude');
plot(x,y,k,g);

When you call plot() or most other graphics calls, if you have not called
hold on
or equivalent, then the first thing plot will do is locate the axes and cla() the axes.
Move the labels and title to after the plot call.

You may modify based on the following code and you should plot first and then set the grid,title,xlabel,ylabel,etc
x = -5:5;
y = 1-abs(x/5);
plot(x,y);
grid on;
title('Task-2 Triangular Signal');
xlabel('Time');
ylabel('Amplitude');
