I would like to create a picture from different pictures, i.e., a photo mosaic. I have 10 sample pictures to create an image of the Mona Lisa. I cropped those pictures to 150*(32x32) from 1*(480x320) for increase sample. I made vectors with those pictures and used k-means algorithm for clustring, but I am stuck.
How can I do this with Matlab?
Here is an example
You can do this by making a GUI-program in Matlab. So fare, you have to implement some functions like these:
function handles = loadImage(handles)
function resizeThumbs(path,thumbSize)
function handles = loadThumbs(handles)
function handles = genMosaic(handles)
If you have further questions ask.

Is it possible to plot bars with filled pattern in Matlab, like this figure?
I attempted to use applyhatch_pluscolor link however, I couldn't make it work (attempt below). Is there an easy / feasible alternative?
Test code:
bar(rand(3,4));
[im_hatch,colorlist] = applyhatch_pluscolor(gcf,'\-x.',1,[],[],150);
Then I changed the source code, from bits = hardcopy(h,'-dzbuffer',['-r' num2str(dpi)]); to bits = print(h,'-RGBImage',['-r' num2str(dpi)]);.
I got the figure below. However, this is still far away form the desired result.

I have simulink block which has thousands of input signal for example which contains a text TRXA
AIM1_Freshness_TRXA_FCC,
AIM2_Freshness_TRXA_FCC
I need to create exact replica of the model only change is TRXA is changed to TRXB
AIM1_Freshness_TRXB_FCC ,
AIM2_Freshness_TRXB_FCC
Any easy or matlab script to do that
Does the following help?
open_system('your_model')
x = find_system('RegExp','on','FindAll','on','Name','TRXA');
for idx=1:size(x,1)
name_orig = get_param(x(idx),'Name');
set_param(x(idx),'Name',strrep(name_orig,'TRXA','TRXB'));
end

I have been trying for a while to get this to work but I don't seem to be getting any closer to a solution.
I'm not sure of what the pattern is and what to write for the "d" value in a:d:b
Clearly you want to start from 0 (a) and go to 2*pi (b).
Now the question comes what is your step size (d)?
From your example you can see that you are changing from 0 to pi/n.
And from pi/n to 2*pi/n.
This means your step size is d=pi/n
Once you defined your n, e.g:
n=10;
you can do the rest like this:
x=0:(pi/n):(2*pi)
y=sin(x);

I want to know is it possible to make multidisciplinary function handle in MATLAB and if possible, how can I do this.
I assume you mean a "multivariate function" since a "multidisciplinary function" is completely non-nonsensical.
f=#(x,y)x+y
f(3,2)
ans =
5

I want to my program give a image to user and user by mouse choose a pixel,then spatial information of pixel return to program for another process.
how write code for it in matlab ?
Try this:
A=imread('your image');
imshow(A);
impixelinfo;
[c, r, vals] = impixel;
c and r are arrays of all the columns and rows of the part of the image that user clicked on and vals are the RGB values of each point.
