    Dear Laura,

    Are you trying to use the SAC's Matlab interface or do you want to
    manipulate data in Matlab.

    If you would like to manipulate data in matlab there are routines to
    do this in (v. 101.2)
    sac/utils/getsacdata.m
    sac/utils/padcat.m
    sac/utils/readsac.m
    sac/utils/sacstruct.m
    sac/utils/writesac.m

    If you would like to use SAC's Matlab interface (running Matlab from
    in the SAC program) this is more difficult. First, make sure the SAC
    was compiled with Matlab support (not the default) and then make sure
    you have the libraries required (libeng and libmex).
