Plot using '-' and '--' in a for loop of calculations

6 views (last 30 days)
syms x
a = -0.25:0.001:0.25
c = a.^2
hold on
for b = 1:500
d = 100+c(b)
g = (100-c(b))
y1 = 10+i*0.05+sqrt(c(b)-0.0001);
y2 = 10+i*0.05-sqrt(c(b)-0.0001);
sol = vpasolve( x^4 - 0.2*i*(x^3) - (2*d+0.0099)*(x^2) + 0.2*i*d*x + g^2 == 0 , x )
hold off
Can plot only using 'color.' with single points. i want the plotting of sol() to be solid (between each others points), and the y1 and y2 to plot using dashed line.
thanks a lot in advance

That is not possible, except by post-processing to locate all of the plot handles and using their relative positions in the axes Children to figure out which of the two lines they belong to, and then construct new lines joining them together.
What you should be doing is recording the values inside the loop instead of plotting inside the loop, and then doing the plotting as a whole afterwards.

thanks! how do i do that, and then plot the actual lines? couldnt manage that, that's why I'm in this problem from the start.
