How to plot a trapezoidal pulse in Matlab?

48 次查看(过去 30 天)
I want to plot a trapezoidal pulse that has user defined rise time and fall time i.e. slope of the edges of the trapezoid can be set by me.

Can you please explain me how it is working, so that I can modify it according to my need. Actually i have to plot it with respect to time and continuous pulse so that it is the reverse in the next period of time like in the image given below

NumMFs = 1;
MF1 = 'MF':'trapmf';[1 3 4 6]
MF1 = trapmf(x,[1 3 4 6]);
Can someone help with this to get the graph in trapezoidal graph? This is very urgent I really need help from all of you

function [] = trapezoidal_pulse (rise_time, fall_time, height, length)
pulse = zeros (2, 4);
pulse(1,2)=height;
pulse(2,2)=rise_time;
pulse(1,3)=height;
pulse(2,3)=pulse(2,2)+length;
pulse(2,4)=pulse(2,3)+fall_time;
plot(pulse(2,:),pulse(1,:))

I have managed to make it work for up to 2 cycles...
function [] = trapezoidal_pulse (initial_height, on_height, delay_time, rise_time, fall_time, time_on, period, cycles)
pulse(:,1) = [initial_height,0];
pulse(:,2) = [initial_height,delay_time];
pulse(:,3) = [on_height,pulse(2,2)+rise_time];
pulse(:,4) = [on_height,pulse(2,3)+time_on];
pulse(:,5) = [initial_height,pulse(2,4)+fall_time];
pulse(:,6) = [initial_height,period];
for i=2:cycles
pulse(:,3+(2*i)) = [initial_height,period*(i-1)];
pulse(:,4+(2*i)) = [initial_height,pulse(2,3+(2*i))+delay_time];
pulse(:,5+(2*i)) = [on_height,pulse(2,4+(2*i))+rise_time];
pulse(:,6+(2*i)) = [on_height,pulse(2,5+(2*i))+time_on];
pulse(:,7+(2*i)) = [initial_height,pulse(2,6+(2*i))+fall_time];
pulse(:,8+(2*i)) = [initial_height,period*i];
end
plot(pulse(2,:),pulse(1,:))

This code should work for more than 2 cycles..
function [] = trap (initial_height, on_height, delay_time, rise_time, fall_time, time_on, period, cycles)
pulse(:,1) = [initial_height,0];
pulse(:,2) = [initial_height,delay_time];
pulse(:,3) = [on_height,pulse(2,2)+rise_time];
pulse(:,4) = [on_height,pulse(2,3)+time_on];
pulse(:,5) = [initial_height,pulse(2,4)+fall_time];
pulse(:,6) = [initial_height,period];
for i=2:cycles
pulse(:,1+(6*(i-1))) = [initial_height,period*(i-1)];
pulse(:,2+(6*(i-1))) = [initial_height,pulse(2,1+(6*(i-1)))+delay_time];
pulse(:,3+(6*(i-1))) = [on_height,pulse(2,2+(6*(i-1)))+rise_time];
pulse(:,4+(6*(i-1))) = [on_height,pulse(2,3+6*(i-1))+time_on];
pulse(:,5+(6*(i-1))) = [initial_height,pulse(2,4+6*(i-1))+fall_time];
pulse(:,6+(6*(i-1))) = [initial_height,period*i];
end
plot(pulse(2,:),pulse(1,:))
example:
trap (0, 1, 0, 1e-1, 1e-1,1 , 2, 5)

i try to above same code...but the function code is error.
how to solve the problem...
function []= trap (0, 1, 0, 1e-1, 1e-1,1 , 2, 5,4)
pulse(:,1) = [initial_height,0];
pulse(:,2) = [initial_height,delay_time];
pulse(:,3) = [on_height,pulse(2,2)+rise_time];
pulse(:,4) = [on_height,pulse(2,3)+time_on];
pulse(:,5) = [initial_height,pulse(2,4)+fall_time];
pulse(:,6) = [initial_height,period];
for i=2:cycles
pulse(:,1+(6*(i-1))) = [initial_height,period*(i-1)];
pulse(:,2+(6*(i-1))) = [initial_height,pulse(2,1+(6*(i-1)))+delay_time];
pulse(:,3+(6*(i-1))) = [on_height,pulse(2,2+(6*(i-1)))+rise_time];
pulse(:,4+(6*(i-1))) = [on_height,pulse(2,3+6*(i-1))+time_on];
pulse(:,5+(6*(i-1))) = [initial_height,pulse(2,4+6*(i-1))+fall_time];
pulse(:,6+(6*(i-1))) = [initial_height,period*i];
end
plot(pulse(2,:),pulse(1,:))
