Thank you so much.... I had a question regarding higher order NDDE s ... how we can solve for example second order natural delay differntial equations ?

[@CollegeVideoFreak]

I am having trouble understanding the matrices in the second example (the system of equations). You said that YL is a matrix with three rows corresponding to the three state variables. That means each element in the matrix corresponds to one of the lag terms from our system of equations. But doesn't each lag term merit a column vector of its own, corresponding to its values at successive times?

great job sir

Hello,
How to plot a figure of a state depend delay differential equation with multi constants history?

[@IrshadAhmad-mg1gm]

Good noon Sir!
Can you please provide a video for the RL integral of the delayed function of the pantograph type??...

[@abdouhenni2588]

Thanks a lot, just a question: How can I delaying a signal in the Matlab script file without using Simulink block? (i want the instruction of delaying a signal in the script file )

Thank you sir for this video. Please help me with the Matlab code of Fractional-order differential equations. Please reply.

Hello Yarpiz, I have the doubt about what is the difference between the lag 1 and the history y=1 in the 07:38,
I am trying to graph a function with an initial condition, my function is: y'=cos(pi*t)*y^2-y(t-tau)=0, tau=1 and y(0)=cos(pi(t+1)), but I am not sure how to introduce the initial condition.
could you help me please?
I did this code, but I am not sure if I am good.
lags=1;
tf=10;
sol=dde23(@ddefunc,lags,@history,[0 tf]);
t=linspace(0,tf,100);
y=deval(sol,t);
plot(t,y)
function yp=ddefunc(t,y,YL)
yp=cos(pi*t)*y^2-YL;
end
function y=history(t)
y=cos(pi*(t+1));
end
Thanks in advance

plse tell me, how solve distributed delay differential eqns through matlab

[@umiumira4916]

hye. can you show how to solve it using hand calculation ? how to find the delay
