Hi Lukasz
I think Roger is right, and the equal sign is not necessary.
The link you provided is only for MUPAD (Link) , which is a symbolic computation GUI in MATLAB. The syntax in MUPAD may not be applicable to MATLAB command window. So, I suggest you change the last line to
>> int(exp(-L*(x-a)^2), 'x', -inf, inf)
MATLAB is indeed very suitable for physics/applied math where integrals need to be evaluated.
If you would like to perform pure symbolic computations, you may type MUPAD in MATLAB command line and do it from there. You may also do symbolic computations in the MATLAB command line, but be careful about the syntax difference between MATLAB scripts and MUPAD.
