Sometimes, manual interaction is simpler than using builtins...

In this example, we parse the arguments as they are occouring, and remove them as soon they are read.
(untested but should work)
Code:
# Sometimes, manual interaction is simpler than using builtins...


# Removing args as they are parsed
for A in $@ ; do
	case $A in
	-b)	shift
		rate=$1
		shift
		;;
	-c)	# Set the vars
		shift
		charA=$1
		numB=$2
		charC=$3
		
		# Remove them from arg list
		shift 3
		;;
	-d)	shift
		name=$1
		shift
		;;
	esac
done

[[ -z $rate ]] && echo "B was passed"
[[ -z $charC ]] && echo "C was passed"
[[ -z $name ]] && echo "D was passed"

What you would need to do, is to check (specialy for -c) if the 'following' arguments, do start with a "-" or otherwise not match.
Remind you, since the -b or -c was already removed, you can simply check (for example) if there are enough (3) follow up arguments by [[ 3 -eq $# ]] inside the case block.

Hope this helps

DESCRIPTION

       Each of these functions performs an in-place multiplication of two vectors and shifts the result.

       For real data, the following equation is used:

       xz[i] = xz[i] * y[i] * 2**(-shift)

       where i = 0, 1, ..., (n - 1).

       For complex data, the following equation is used:

       tmp	   = xz[2*i]
       xz[2*i]	   = (tmp*y[2*i] - xz[2*i + 1]*y[2*i + 1]) * 2**(-shift)
       xz[2*i + 1] = (tmp*y[2*i + 1] + xz[2*i + 1]*y[2*i]) * 2**(-shift)

       where i = 0, 1, ..., (n - 1).

PARAMETERS

       Each of the functions takes the following arguments:

       xz	       Pointer to the first element of the first source and result vector.

       y	       Pointer to the first element of the second source vector.

       n	       Number of elements in each vector.

       shift	       Right shifting factor.  The ranges of valid shift are:

		       1 <= shift <= 8	 for U8, S8, U8C, S8C types
		       1 <= shift <= 16  for S16, S16C types
		       1 <= shift <= 31  for S32, S32C types

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
