+ -- Function File: [YHAT, LAMBDA] = regdatasmooth (X, Y, [OPTIONS])
+ Smooths the Y vs. X values of 1D data by Tikhonov regularization.
+ The smooth y-values are returned as YHAT. The regularization
+ parameter LAMBDA that was used for the smoothing may also be
+ returned.
+
+ Note: the options have changed! Currently supported input
+ options are (multiple options are allowed):
+
+ `"d", VALUE'
+ the smoothing derivative to use (default = 2)
+
+ `"lambda", VALUE'
+ the regularization paramater to use
+
+ `"stdev", VALUE'
+ the standard deviation of the measurement of Y; an optimal
+ value for lambda will be determined by matching the provided
+ VALUE with the standard devation of YHAT-Y; if the option
+ "relative" is also used, then a relative standard deviation
+ is inferred
+
+ `"gcv"'
+ use generalized cross-validation to determine the optimal
+ value for lambda; if neither "lambda" nor "stdev" options are
+ given, this option is implied
+
+ `"lguess", VALUE'
+ the initial value for lambda to use in the iterative
+ minimization algorithm to find the optimal value (default = 1)
+
+ `"xhat", VECTOR'
+ A vector of x-values to use for the smooth curve; must be
+ monotonically increasing and must at least span the data
+
+ `"weights", VECTOR'
+ A vector of weighting values for fitting each point in the
+ data.
+
+ `"relative"'
+ use relative differences for the goodnes of fit term.
+ Conflicts with the "weights" option.
+
+ `"midpointrule"'
+ use the midpoint rule for the integration terms rather than a
+ direct sum; this option conflicts with the option "xhat"
+
+ Please run the demos for example usage.

+ -- Function File: [YHAT, V] = rgdtsmcore (X, Y, D, LAMBDA, [OPTIONS])
+ Smooths Y vs. X values by Tikhonov regularization. Although this
+ function can be used directly, the more feature rich function
+ "regdatasmooth" should be used instead. In addition to X and Y,
+ required input includes the smoothing derivative D and the
+ regularization parameter LAMBDA. The smooth y-values are returned
+ as YHAT. The generalized cross validation variance V may also be
+ returned.
