Dear Mahmood,
The best way to convert miniseed to SAC is outside Matlab using the IRIS tool mseed2sac: https://seiscode.iris.washington.edu/projects/mseed2sac
which works for Windows/Linux/Mac.
Install this code and from Matlab, call it using the system() function.
Cheers,
François

Dear Vinod,
SRTM .hgt files are freely available at http://dds.cr.usgs.gov/srtm/version2_1
Once downloaded, a single tile (1 by 1 degree) is coded as a simple matrix of 1201 by 1201 binary int16 values, big-endian. No header. Integer values represent elevations in meter. -32768 value means "no data".
For SRTM1 tiles (USA territories), tiles are 3601 by 3601.
That's all. See online documentation for further details but this is easily readable in any language.
Regards,
François.

Dear John,
Yes, you missed the required version of Matlab (2014a) which contains a new function "strjoin".
I just updated the script to improve compatibility with older versions of Matlab. Please let me know.
François.

Thanks Dicky,
The time vector is in datenum Matlab format (see datenum for description). You must apply the command:

datetick('x')

after plotting the data to have time labels (see datetick function).
