[SAC-HELP] matlab

[Brian Savage]

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).
