We can't give an algorithm until you indicate what values are to be input and what values are to be output.

Assuming that you may not have the Symbolic Math Toolbox, this should get you started:
syms A E(x) Z b c d E0
Eqn1 = -diff(E,x)/p == (3574/A) * E^(-b) * Z^(c*log(E)+d);
SEqn1 = dsolve(Eqn1, E(0) == E0); % E(0) == E0, initial condition
SEqn1 = simplify(collect(expand(SEqn1)));
E = matlabFunction(SEqn1)
produces:
E = @(A,E0,Z,b,c,d,p,x)(-(Z.^d.*p.*x.*3.574e3-A.*E0.^(b+1.0).*exp(-c.*log(E0).*log(Z))+Z.^d.*b.*p.*x.*3.574e3-Z.^d.*c.*p.*x.*log(Z).*3.574e3)./A).^(1.0./(b-c.*log(Z)+1.0));
The rest is yours to solve, since I haven’t shot a proton at a target in a very long time.
It looks rather straightforward, otherwise.
See the MATLAB Online Documentation for details.
