Hi, as a new user of Matlab, I have been faced with the following problem. I am doing error propagation, and lets say that I have the following situation:
1) I make a scatterplot of 20 points on a non-log, x-y plot. 2) I use c2=curvefit(x,y,1) to fit the least squares line 3) I have to use the slope of this line in further calculations, and would like to know how to take the error of the slope into account. I know that it is not simply corrcoef(x,y) but that I need something like: The slope = 2345.6 +/- 43.3
How can I get a +/- like shown above? I looked through Traver's Tutorial, as well as the one by Sigmon, and the MIT help docs, and couldn't figure out how to do this. If someone could help, I would greatly appreciate it.
