This function is generic (see Methods);
method functions can be written to handle specific classes of data.
Classes which already have methods for this function include:
wp.crystal.
USAGE:
convup(x, filter, boundary, odd=F, convfast=F)
REQUIRED ARGUMENTS:
x:
a numeric vector or an object of wp.crystal.
filter:
a vector of filter coefficients. When x is an object of wp.crystal,
this argument can be optional.
boundary:
a character string giving the name of the boundary rule, e.g., "periodic".
See convdown for details. When x is an object of wp.crystal,
this argument can be optional, the default is attr(x, "boundary").
OPTIONAL ARGUMENTS:
odd:
logical flag indicating if the outcome vector should be of odd length.
See details below.
convfast:
logical flag indicating if fast algorithm should be used.
VALUE:
if odd=FALSE, then a vector of length 2n, where n=length(x), is returned;
otherwise, a vector of length 2n-1 is returned.
DETAILS:
See the printed help file for the equation that determines the output vector.
