According to my previous question, I have changed the generate command to:
and got the following picture:
Now I want to test a wavelet transform on the same signal, which of course exists in Matlab, but I have one thing which I should clarify: generally, as I know large scale values correspond to small frequencies and small scale values to large frequencies. So, how should I determine if the given frequencies are small or large? Also, which wavelet transform should i use?
and plot it
How should I read the second picture? What kind of information can I get?
