syms h r v(x)
h = 4.5
g = 4/pi
A = pi
expr = [h^2*(diff(v, 2)+2*i*h*diff(v) - g == 0)];
Dv=diff(v);
cond = [v(0) == 0,Dv(0)==0];
sol = vpa(dsolve(expr,cond),4)

This should not give any error. What is the complete error message?

Based on the longest of the Tags you specified:
attempt to execute script dsolve as a function: c:\users\dell\desktop\matlab2019\dsolve.m error in untitled1 (line 112) sol = vpa(dsolve(expr
you've created your own dsolve.m script that's taking precedence over the dsolve function in Symbolic Math Toolbox. Rename c:\users\dell\desktop\matlab2019\dsolve.m so it no longer conficts with the dsolve function written by MathWorks.
