Here i tried to plot a sybolic equation for range x=[1,20] but it shows
How to fix it .and plotting the curve

syms eq(x)
eq(x) = (sin(sqrt(x)+5)*exp(sqrt(x)))/sqrt(x)
fplot(eq,[0 20])

If i want to get all the intersecting point of x axis for a particular range like the graph below.For instance here the intersecting ponit is in range of 1 to 400.
how to get that ?
Thanks in Advance
I think you want to use vpasolve. It does not appear to be able to return all solutions at once, so you'll have to define intervals to search in. See this example.
syms x
eq = (sin(sqrt(x)+1)*exp(sqrt(x)))/sqrt(x)==0
vpasolve(eq,x)
% restricting range
vpasolve(eq,x,[0 10])
vpasolve(eq,x,[10 30])
