Hi john,
Can you help me out ?
Right now all the values only allow me to find the peaks of the waveform
What about show the x value and the y value on the selection portion of the waveform ..instead of showing just the peak .
Can you do that ?

 

to show x value on graph???

to calculate x value would do this
like lets say the peak is at 90
y is the function
therefore find when the function is equal to 90 use this command.
z=find(y==90)
that will give you an indice or element. whatever you call it.
then simply put x(z). there is your x value. if want to plot point on graph. just look up how to plot point. then just put z & 90. and there you go.

 

hey guys, pls let me know how to process a signal?
as in i recorded my own sound ,which will then be stored as a matrix.
then using wavwrite function i converted tat to a wav file.
now what does processing of this signal means?
also i tried applying fourier transform to it,but i dont know where to proceed further.
my project aim is speech recognition.
