The syntax that you are probably looking for is : errorbar(x,y,err) , where :
- x - data points for the x coordinate (in this case rate perhaps)
- y - data points for the y coordinate (in this case konc (conc?))
- err - error bar lengths (assuming you want symmetric bars)
The documentation gives a more exhaustive description of the various options that are available. You can take a look at the error bar documentation here: https://www.mathworks.com/help/matlab/ref/errorbar.html .
