# What is the delta parameter in $\tt scal2freq$?

I am running complex morlet (cmor1-1.5) wavelet transform. I want to have the transformation for the range of $[1,150]\textrm{ Hz}$ with a step of $1\textrm{ Hz}$. I want to use scal2freq Matlab function to convert scales to pseudo frequencies but I don`'t know how to define the delta.

The delta argument in the scal2freq MATLAB function is the sampling period that relates to the data sampling frequency (i.e. delta = 1/Fs). A good description of this function can be found here: http://au.mathworks.com/help/wavelet/ref/scal2frq.html it also includes an example including how to calculate and define the delta argument. I hope this helps!
