Very nice! Works exactly as advertised and will be very useful.

16 Dec 2013 Linear Deming Regression deming perfoms a linear Deming regression. Useful when errors are present in both x and y variables. Author: James Hall Huang, Hilda

very nice! I have a quick question: is it possible to add in some functions to provide the option of forcing the intercept to zero?

... (meant to say "off by a factor of approximately sqrt(n).")

This is a nice script, but there appear to be a couple bugs regarding the calculation of confidence intervals.

First, a minor typo: on line 122,
if nargin < 5
should be
if nargin < 4

More significantly, on line 167,
stats.s_b = std(b_sub,[],2);
should be
stats.s_b = std(b_sub,[],2)*(n-1)/sqrt(n);

Without the latter bug fix, the confidence intervals that deming.m computes are off by a factor of sqrt(n).

Great tool. I modified your function by adding drawnow() right before enabling colorbar() (at the bottom of the program) so that the plot won't get shrunk unjustifiably when I rescale the figure. Hope it'll be useful info to you.

Very useful. Good documentation and design. Thank you
