Just great!

I was not able to run this on Matlab 6.1, so Release 5.2 seems to be an error. Matlab 6.5 has regexp, but one which doesn#t support 3 argins.
Nevertheless the mfile is very simplistic, all subdirectories are used, but only the first level of a possible tree, and certain directories like @ or private or ., .. are included.

I have tried using the matlab uitable object to house the data, it prints, but it will always go out of position when being printed since the table is hard anchored on the figure and moves to unintended location when it prints due to resizing issue.

Nice function, Michael. I can see this will be very useful.

I found some bugs, though. Try this example:

sampleTimes = [1:200];
RPM = [600+rand(1,100)*500, 9000+rand(1,100)*2500];
breakplot(sampleTimes, RPM, 1500, 8500, 'Line');

I get an error in line 142 with the RESHAPE function.

One question, I don't quite understand the reasoning behind how you get the yticklabel. Can't you simply do this?

set(gca, 'yticklabel', num2str(ytick'));

This should clearly be an option in matlab! Can you make it plot the axes labels in the plot also?

Thank you very much!

hello
i have a large text file.
that size is about 75 Mb and it has headerline.
Now i want to import that file in matlab and use of that for input in neural network tools. but i can't import that text file.
please help me

very usefull, but unfortunately this error occur when i tried to run the program:

??? Error using ==> actxcontrol
Control creation failed. Invalid ProgID 'MSFlexGridLib.MSFlexGrid.1'

Error in ==> graph_and_table at 148
h.grid = actxcontrol(...

:(

How can I make another sheet tab active ('Sheet 2' instead of 'Sheet 1' for example)?

Mathworks needs to rapidly implement a more refined version of this popular type of plot. In the mean time, this code is VERY useful. Thanks!!

extremely useful... keep posting stuffs like this so tht novice like me will find it really useful.

how to access the datas inputed by the user in the spread sheet in my mfile. is there direct methods to access by giving the corresponding cell name??

There is a minor error in this program,

Awesome little script. Well documented, and easy to modify to pick a point from plots with multiple lines. Thanks!

Found a few bugs,
% MaxR = min(L,MaxR); % orginal from Author
% MaxC = min(W,MaxC);
MaxR = min(L,MaxR) + MinR -1; % fix
MaxC = min(W,MaxC) + MinC -1;

basic guidelines express in a lucide manner

Excellent! very helpful function!

very efficient, and useful. Nice work

Timing a single loop is not accurate. To time performance, you need to do several iterations with a large dataset. Using a (slightly) modified version of your code, the time it takes to determine the mode of a 10,000 random element: >> data=rand(10000,1); y=mode(data);
yields the following timing results (where I surrounded both methods with a for i=1:1000 loop:

Hist method: 9.49, 9.61, 9.53secs
Non-hist method: 3.23, 3.32, and 3.20secs

I swapped the order (both loops ran in same function) and the timing remained the same.

Command line I used and results:
m=mode(data);
Elapsed time is 9.489020 seconds.
Elapsed time is 3.234487 seconds.
>> m=mode(data);
Elapsed time is 9.606668 seconds.
Elapsed time is 3.318920 seconds.
>> m=mode(data); % Order swapped (non-hist first, hist second)
Elapsed time is 3.197718 seconds.
Elapsed time is 9.529675 seconds.

mode.m:
--------------------
tic;
for i=1:1000
sorted=sort(x(:));
[d1, i1]=unique(sorted);
h=diff(i1);
[d2, i2]=max(h);
m=d1(i2);
end
toc

tic;
for i=1:1000
[b,i,j] = unique(x);
h = hist(j,length(b));
m=max(h);
y=b(h==m);
end
toc

The mode function seems to return only one solution when there are more than one solution, e.g. X = [1 1 0 2 3 3]; this function only returns 1. It should 1 and 3.

Here I give a little bit modifications

function y = modestat(x)

[b,i,j] = unique(x);
[m,k] = sort(hist(j,length(b)));
id = find(max(m) == m);
y = k(id);

FYI, here's a corrected version of Harold's suggestion above:

sorted=sort(data(:));
[d1, i1]=unique(sorted);
[d2, i2]=max([i1(1); diff(i1)]);
m=d1(i2(1));

Thank you! You are very observant! Also, let me note that there will soon be an update to this submission that will correct some problems. In the original version, users may encounter problems with only one assumption and some users may have a problem opening the PDF documentation. Those of you who have downloaded the file may want to check back in a few days.

Excellent reader, but consume too much memory for large files
