question about fplot function
2 views (last 30 days)
hey! i have a question about fplot.
I am stuck with this problem since many hours. I solve a differential equation but i have to plot it but it dosent work. can someone please help me what im doing wrong?
my code looks like this.
Dy = diff(y,x,1);
DDy = diff(y,x,2);
ysol = dsolve(DDy + 3*Dy == 12*x - 5, y(0) == 1,Dy(0) == 0)
