I am using basic curve fitting for the first time in a while and I get a bunch of equations of the form:
y = 6.588e + 06x^2 +4028x - 1.066. Can someone tell me what the "e" is in the first term?
Thanks
Peter

Scientific notation.
6.588e + 06x^2 == 6.588*10^6 * x^2
Note that it is easier and faster to write, and even a bit easier to read once you learn it. This is commonly used all over MATLAB. For example:
x = 2.3*10^12
x = 2.3000e+12

That was a snip of the output from the Basic Fitting tool that I got to from the tool menu in Plot in version R2024b on a Mac (maybe I need update). Here is the plot and the output together:

Also, now that I look at the image here, I see the version of the equation on the plot itself, and that is certainly clear.
Thanks everyone.
