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.

    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
