A2name  R Documentation 
This function returns a character string according to a particular format for naming D2Amat objects.
A2name(J, filter.number, family, switch = "direction")
J 
Discrete autocorrelation wavelets will be computed for scales 1 up to scale J. This number should be a negative integer. 
filter.number 
The index number of the wavelet used to build the PsiJ/PhiJ object. 
family 
The wavelet family used to build the PhiJIE object. 
switch 
Allows the user to define how they wish their inner product matrix to be formed. There are two available options:

Some of the matrices computed by D2Amat take a long time to compute. Hence it is a good idea to store and reuse them. This function generates a name according to a particular naming scheme that permits a search algorithm to easily find the matrices. Each matrix has three defining characteristics: its order, filter.number, family and the method of construction of the matrix (switch="direction" or "level"). Each of these characteristics are concatenated together to form a name.
A character string containing the name of a matrix according to a particular naming scheme.
