x = [0:.1:5];
w=1;
t=2;
lm=233*10^-9;
k=2*pi/lm;
f1=sin(k*x-w*t);
f2=sin(k*x-w*t);
f=f1+f2;
plot(x,f);
There is an output.i dont know this is wrong or right.but the output should be periodic black and white lines.. I tried
onematrix=one(size(f));
om2d=onematrix.*f
imagesc(om2d)
colormap(gray)
but there is an error
??? Error using ==> mtimes
Inner matrix dimensions must agree.

What does x and t represent? And w, k, and lm? All you're doing is summing the same sine wave, so f is just simply 2*f1 since f1 and f2 are identical. If you're trying to modulate one waveform by the other, see my attached warbling sound demo, and Moire pattern demo (which probably requires the Image Processing Toolbox).

x is distance,t is time,w is omega,k is wave number.
we can have two omega and time for two sinewave
i have to add two sine wave and plot that with varying distance not time...
then the output's haar wavelet transform
on which equation the program will be done is
f =sin(kx-wt);
