This is how you plot using rsac.m

Z = rsac('my.SAC');
plot(Z(:,1),Z(:,2))

Column 1 in Z is time, Column 2 in Z is amplitude/counts.

However, if you get an error about endean being the opposite, look in rsac.m as to where the endean is declared (big/small) and change it. 

Your header variables are stored in the 3rd column of Z matrix. You can find these here,
http://web.utah.edu/thorne/saclab/ch.m 

For example, if you want delta stored in Z (in the matrix output, line 1),  you would call for it with something like    
dt = Z(1,3).
e.g. line in rsac.m or ch.m
if input == double('DELTA   '); output(1,3) = varargin{i+1}; end

dear all,

i've read and download all matlab's file in
http://web.utah.edu/thorne/software.html


currently, i'm using ubuntu 12.04, sac.106 and matlab 7.14

i've tried to execute rsac.m and p1.m in matlab, but i've error's message as below:

>> rsac
>> p1
Index exceeds matrix dimensions.

Error in p1 (line 44)
[a,b]=size(varargin{nargin});

Before executing these files, i've renamed my sac's file to be varargin.sac.
However, this error's message always come up in matlab's message.

please help me to solve this error.
