There is a direct command in matlab for images subtraction i.e.
I = imread('rice.tif');
Iq = imsubtract(I,50);
You can use any weighing factor with that.

first you need to define n , as a matrix
n= 1 : 1 :128 ;
and then write down the equations
and then if you want to plot the two signals in the same graph you use:
that for example how to use multiplpot figure

you can use subplot(N,1,n), plot(...), xlabel(' '), ylabel(' '), title(' ') for each

You can also use subplot if you want to plot in different windows but shown at the same time.

Try this -- copy and paste it into your matlab command Window.
The middle section does the ifft. The other sections simply create some input data, and plot the results. You may want to modify the tweaks at DC and Nyquist, depending on how your measurement hardware behaves at those points.

I'm not sure I understand what you mean by "look at just one period", but maybe this example will help you. It generates a frequency sweep, and then tabulates the waveform's positive-slope zero-crossing points. You can copy-and-paste the code directly into your matlab command Window.
% Frequency sweep
F0 = 10; % start frequency, Hert

Maybe this small example will help you. It generates a sinewave frequency sweep, and then plots and tabulates the waveform's positive-slope zero-crossing points.
% Frequency sweep
F0 = 10; % start frequency, Hertz
F1 = 100; % stop frequency, Hertz
T = 0.5; % duration, seconds
FS = 1000; % sample rate, Hertz

>> N= 200;
so , how to add noise to this coading ???????? pls send me reply. thanks
What type of noise do you want, if you want white noise, use the awgn comman

What did u mean by align? If i understood correctly , you can use subplot command it works for imshow too.

hi, Try the following code
//To create the 2D domain:
//The coordinates are ready, type the function
z=x.^2+y.^2;//Or Any function of X
// To plot it, See all the types and choose what suits you

Hi, I have an homework for this tuesday and I have to do that in 2 days.:cry:
Here is the question: (People who know matlab and can understand what the question says..help me please!)
Consider the function f(x)= sin(pi*x/2). Expand f(x) in a Taylor series about the point x0=0 and do the following?
a) Estimate the number of terms

This works fine for me in Windows. It captures stereo and displays left and right waveforms:
y = wavrecord(5000, 22050, 2);
Be sure your operating system's audio mixer is set properly.

can i ask something...
how ca i change this command to display the magnitude spectrum??
this command has show low pass filter..
handle=errordlg('wp must be less than ws for lowpass filter','guifilter_design');

You can zoom in on a particular region of your plot by using the magnifier icons at the top of the figure window generated by the subplot() function. If you select "zoom in" and then left-click in the plot area, a menu appears. Under "zoom options", you can choose to constrain the "zoom" to only the horizontal or vertical axis. I frequently use
