Trend lines
显示 更早的评论
Hi, I am trying to plot linear trend lines for a number of data sets and determine their respective gradients. Is there any way of doing this without using the 'tools,basic fitting' tab in the figure? Doing this for every plot will be quite time consuming. Sorry, I know this is probably a pretty basic question, but I'm pretty new to Matlab and would really appreciate any help. Thanks Chloe x

...Or to streamline the polyfit -> polyval -> plot process, polyplot does it all in one step, just like this:
polyplot(x,y)
You can also include any line formatting commands, just as you would with plot. For example,
polyplot(x,y,'r--','linewidth',3)
