This function is called by cddews to extract the detail coefficients from an object of class imwd.
getdata(imwd, switch, co.type = "sqr", verbose = FALSE)
An array which can be used by cddews.
An object of class imwd.
Dictates whether the extracted information is structured by "direction"
or
"scale"
.
Dictates the coefficient type which is used. For cddews this must be "sqr"
.
Allows certain informative statements to be printed to the screen
