Solve equation numerically Matlab-Mupad

I am using Matlab, and I am considering to use Mupad to solve next differential equation:

x^2+16*Kn_e*x-1-16*Kn_e-16*Kn_e^2*log(1/x)-m*64*beta(1-zv)=0

I am not sure how to define command for solving it in Matlab, so I choose Mupad, but I also have problems. From my knowledge I can define command in this way:

    numeric::solve(x^2+16*kne*x-1-16*kne-16*kne*kne*log(1/x)-m*64*beta*(1-zv),x)

How to define variables

Kn_e, m, beta

before my command `solve`? And how to define

z_v

in Matlab I would write

zv=0:0.001:1

but here it would not accept it. With that command for zv I got the error

`Symbolic parameters are not allowed in nonpolynomial equations`.

Also how to plot this in format which is compatible with Matlab diagrams which I get from plot command?
