Homework Statement
hi i have the folowing data i would like to plot in matlab
plotERRLW =
0.0466 0.0111 0.0074 0.0046
NX =
50 500 1000 2000
i am using a logarithmic graph to gain a straight line, if i wished to find the gradient of the line would i use the change in the original numbers or change in the numbers after i have taken a log of them?
(also if i have to take a log of them what base does loglog naturally plot)
i have tried a number of options already but can't seem to get the correct answer (i know it should be close to 2) thanks in advance
Homework Equations
i believe the data is of the form plotERRLW = NX^(alpha)
The Attempt at a Solution
so far i have been taking the log base 10 of the numbers in question and simply dividing the log of the error with the log of NX
thanks in advance kyle
