hey guys, what would be the best way to draw a triangular wave?
I just need one triangular wave so my attempt was to draw the left side of the peak of something like y = 2x -8
and right side y = -2x + 8 or something and combine the two, but then I dont know how to make that into one function or graph?

Hi Soloby,
You just asked a question on fuzzy logic, I assume this is in the same area!
Have you tried trimf or trapmf membership functions?

you made a mistake defining x
x = 1:0.1:10
not
x = 0:10:0.1 % this is wrong

See my attached demo
% Creates triangle waves two ways, one using repmat() and
% one using sawtooth() from the Signal Processing Toolbox.
