data=importdata('yourfile.txt');
Use the data as is...
doc save % and friends to write/read .mat files...
If the data in the text file contain more formatting, etc., than just the simplest, then
doc textscan % and friends
help iofun
will give a list of all the choices (a veritable plethora from which to choose depending on what you have as the input format).

Presuming it's actually hex as it appears, use one of the formatted input functions such as
doc textread
doc textscan
doc fscanf
and the hex format descriptor string '%x'
If you know anything about C, that's helpful as Matlab uses its notation and i/o based on the C library. If not, the formatting descriptors are described fully in the fscanf documentation.

when usinf importdata in Command line it works, not from within a script. The variable does'nt show in workspace.
In a script is the same as at the command line. If you mean a function m-file, yes, variables are local in scope within functions; to return the variable to the calling scope (command line or calling function), that function must have a return variable and the result of the read operation, whatever routine you use, returned to the caller via that variable.
See
doc function
for how functions work...
