dear friends
how i can find the integral in the attached photo by MATLAB
fun = @(t) exp(-t.^2)/(t+1);
q = integral(fun,0,inf)
%%ı tried to write it in this way also but i couldnt have asolution
syms a t x
fun2=exp(-2*t.^2)/(t+1);
sol1 = int(fun2,t,0,inf);

For x = 1, MATLAB and Maple both give a MeijerG based result; Wolfram Alpha (Mathematica) times out trying to compute it in the free version.
For x not 1, none of the three will find the solution shown -- which, after all, just substitutes one indefinite integral for another.

you need to vectorise the division as well as the exponentiation:
fun = @(t) exp(-t.^2)./(t+1);
↑ ← VECTORIZE HERE AS WELL
q = integral(fun,0,inf)
q =

Calculate one term where j=0. The result will be 0 if the term is 0 and otherwise will be infinity times the sign of the term. You have posted an infinite sum whose terms do not vary with the variable of summation so you will either get +inf, 0, or -inf
