  1. MATLAB has no implied multiplication. All multiplication must be explicit with either the .* (corresponding elements, which is usually the desired operation) or * (inner product) operators
  2. e to a power is coded as exp() the power
  3. division is the ./ operator with the / operator being more like multiplying by the pseudo-inverse
  4. powers other than e to something, should be the .^ (element at a time) or ^ (matrix power through generalized inner product) operators.
  5. square root is usually most clear and efficient using sqrt() but .^0.5 or nthroot() can be used, and sometimes sqrtm() or ^0.5 are appropriate
For the kinds of equations that are shown here, use .* and ./ and .^ instead of * and / and ^

The equations that were posted have no E3, E4, or E5, so this does not appear to be an answer to the question that was put. How are people to understand this as a solution to the question ?

Ran in:
Caution: you have variable names Q_min and Q_max but you are integrating with respect to log(Q) so Q_min and Q_max are limits on log(Q) not limits on Q.
Integrating with respect to a function instead of a variable is always tricky.
Pi = sym(pi);
syms a_0 E G_fi(Q) Q_max Q_min R sigma_Born T log_Q
eqn = sigma_Born == 4*Pi*a_0^2/(T/R) * int(G_fi(exp(log_Q))/(E/R), log_Q, Q_min, Q_max)
eqn =

See the documentation for the ODE solvers. I'd start with ode45 and the pages listed under Topics at the end of that page.

would be
kummerU(1/2, 5/4, tau_0.^4 ./ (32 .* log(2).^2 .* sigma_k2.^2))
kummerU
This might require the Symbolic Mathematics Toolbox

"A function can be recovered from its Fourier series, under suitable conditions. When this is possible, the Fourier series provides the inversion formula: "
and look at the formula there. Now let lambda = -1/P ...
