Hello everyone,
i have this txt file, and i want to import it inside matlab, as a matrix, in order to extract the data i need.
this should be the same every time i import this kind of text file.
i need that alla the words have to be in a same column and also the numbers, in order to extract them easily and use for calculation
Thank you all!

Things like that will just have to read line by line and parse -- if it is the same format of titles but differing bodies, then taking the one and using it to create a template would probably be about as good a way as any; it's too irregular to do much else with.
I'd be looking to see if there's any possible way to get the output in a more useful format first...maybe there is an option to create a file for import into something else already???
If not, enjoy...it will be tedious, but not terribly difficult to split lines and extractAfter, but the oddball pieces between sections, etc., will be one-of-a-kind to handle, hence the idea of a template.
Now, if descriptions either change names or there are different fields between files, it becomes a whole lot more of a challenge.

This segments some of the file information into 31 individual cells of character vectors . I have no idea what you want from this file (and I do not understand the information in it), so I leave aubsequently parsing it to you.

******************************************************************************* TIME Barycentric Dynamical Time ("TDB" or T_eph) output was requested. This continuous coordinate time is equivalent to the relativistic proper time of a clock at rest in a reference frame co-moving with the solar system barycenter but outside the system's gravity well. It is the independent variable in the solar system relativistic equations of motion. TDB runs at a uniform rate of one SI second per second and is independent of irregularities in Earth's rotation. CALENDAR SYSTEM Mixed calendar mode was active such that calendar dates after AD 1582-Oct-15 (if any) are in the modern Gregorian system. Dates prior to 1582-Oct-5 (if any) are in the Julian calendar system, which is automatically extended for dates prior to its adoption on 45-Jan-1 BC. The Julian calendar is useful for matching historical dates. The Gregorian calendar more accurately corresponds to the Earth's orbital motion and seasons. A "Gregorian-only" calendar mode is available if such physical events are the primary interest.
