linestyle problem while using plot.

[Jinzhi Lei]

Hi, all,

I'm new to  Octave, and have a problem while I try to use plot. It seems that the
'linestyle' option doesn't work with plot at it does in matlab.

I use

plot(X,Y,'linestyle','--');
print -deps test.eps;

to plot the curve and export to the file test.eps. However, when I open test.eps, the curve is not plot in dashed line, but a solid line.

When I plot two curves as follows:

hold on;
plot(X,Y,'r-');
plot(X,Y,'b-');
print -deps test.eps;

the second curve always appear as dashed curve. 

It seems that I can't control the line style by myself. If any one an tell me how to resolve this problem? Thanks.

Jinzhi.

Subject: echo command and functions

I have tried using "echo" to get octave to display what it is reading and what
it is doing while it runs a simple matlab program:

octave:4> run Image_preparation_withoutlandremove
+ % Rawdata read-in program.
+ % The parameter 1: the pitch length;
+ % The parameter 2: start position;
+ % The parameter 3: number of tracks;
+ % The parameter 4: The forth is pixel number for one period of scan;
+ % The parameter 5: The path to the folder keeping rawdata
+
+ % ILscan1 = Getting_RawData_single_channel(0.015,-42,2400,12500,'C:
\Data\Patrick\custom1038-2155\scan1\');
+  ILscan2 =
Getting_RawData_single_channel(0.015,0,2800,12500,'/home/praedor/smb4k/bind222-ml/Data/Patrick/custom1038-2172/scan2/');
error: fscanf: invalid stream number = -1
error: called from `Getting_RawData_single_channel' in
file /home/praedor/Documents/BioCD/custom1038-2172-4-08/Getting_RawData_single_channel.m
near line 39, column 10

So echo is only spitting out information on the program called
Image_preparation_withoutlandremove but the error I am trying to
analyze/figure out is in the function "Getting_RawData_single_channel.m"
which is called within the Image_preparation program.  Is there some way to
get echo or any other command to spit out the details of what it is doing as
it enters "Getting_RawData" rather than only what it is doing within the
calling program "Image_preparation"?

I have also been playing with various debug commands but it doesn't appear to
give me the information I seek.
