Unable to find the maximum value in the following expression

In the following code I am not able to get "pOUT"

w=15;% w is the beamwidth in degrees. It is used in eqns 9,10,11 for
the antenna pattern and gain distributions.
g_main=100;
g_side=0.01;% these are the values of maximum gain and minimum gain
for the ideal sector antenna. Used in eqns 9,10,11 as mentioned above
OmegaOUT=1/30;deltaOUT=5.2;% these are the parameters of equation 6
OmegaLOS=0;deltaLOS=1/67.1;% these are the parameters of equation 7
syms z;assume(z > 0);% this is for defining the variable z for distance between transmitter and receiver
pOUT=@(z)(1-OmegaOUT.*exp(-deltaOUT.*z));

Are you sure the expression is correction?

pOUT=@(z)(1-OmegaOUT.*exp(-deltaOUT.*z));

YOIu can delete syms you need not to use it there.

solve(pOUT) % remove @(z) maybe you want to solve for z
