Dear All
I am trying to superimpose 2 plots using the hold on option.
e.g.
.
.
.
[X,Y]=meshgrid(x,y);
PIC = surf(X,Y,a);
view(0,90);
.
.
hold on
plot(20,30,'ro');
My problem is how can I increase the size of these red circles, and how can I
make large bright red spots rather than small red circles?
thanks
Ravi.

You can set line properties of line with the plot command:
plot(x, y, property, value, property, value .). Check doc
plot for more details.
The properties you want to use for the makers are:
MarkerSize, MarkerEdgeColor, MarkerFaceColor.
Hope it helps.

Hi, There,
I have some data in *.txt format.
They are saved as follows.
***************************************
The data is collected on Jan 1, 2006.
Sampling frequency is 2560Hz.
No load.
Column1 Column2 Column3
0 1.02 1.10
0.001 0.81 -0.9
... .... ...
******************************
I want to load the data
0 1.02 1.10
0.001 0.81 -0.9
... .... ...
Anyone can give some suggestions?
Thanks a lot.
Frank

There are multiple methods of doing this.
The easiest is
1.) Open the file
fid = fopen('file_name.txt','r');
2.) Scan in the file data
[raw_data,count] = fscanf(fid,'%f',[NumCol inf]);
where NumCol is the number of colums of data
inf is for the number of rows (dosn't need to be specified)
Count gives you the total number of data points, raw_data is your data
array.
3.) close out your file
fclose(fid);

Hello,
I have been suscripted to this lits recently. I would like some help
to implement a algorithm from paper
"A Phase Reconstruction algorithm from Bispectrum" SALEH ALSHEBEILI
& ENIS CETIN, IEEE Transaction on geoscience and sensing, vol 28, nro2,
march 1990.
Link of file pdf:
http://ieeexplore.ieee.org/iel1/36/1766/00046695.pdf?arnumberF695
If anyone can help me or assit to implement this algorithm ,
please replay me. I have some problems to map from mathemtics language to
matlab language.
Regards,

Hi
Use dlmread('file.txt',' ',5,0) ... this should work.
Here 5 denotes the number of row where the data
starts.
For the header you can use textread('file.txt','%s')
and parse the required header text.
or just for header you can use --
fid=fopen('file.txt','r');
for i=1:NoOfTheRowsOfTheHeader
header{i}=fgetl;
end
%% now you will have 4 header line in the cell header
Hope this will help

Try using simply textread function. This function put
all the data in an array following a delimiter. In
your case, no demiliter. Then when you use
textread('file',4,0) you will get
45
data
90
data
...
use for loops to extract the required data
