The main problem is that I have no idea what I am doing. But second to that I am attempting to fit a curve to some data using the equation
y = ((1/A(x-B)^(C+1))+D)^-1
if that makes sense
I need to get the values for A,B,C and D and so have been looking into lsqnonlin but I am having...
I'm doing a PhD in england and am worrying that I have gone into the wrong subject area(organic electronics), I only have a year left and feel like I can complete it but find myself drawn away from my subject area (i originally did a physics degree).
What do you think I should do...
Can anyoune tell me how you flip a column in origin so you are reading it from bottom to top? I don't mind if it means making a new column.
Or if this isn't possible then is it possible to do a differential when taking the bottom values first??
If that makes any sense
Dispersion relation and lattice constants
I need to be able to calculate the period (which I believe is the lattice constant) for a 1D crystal given the energy wavevector relation. Is this possible?
I also have to find the Bravais lattice of a 2D crystal give a similar relation.
What is it...
I have a set of data for an absorption spectra that I plot the firtst derivative of and it gives me a gaussianish plot, I then want to fit it with a gaussian and what i've been doing so far is calculating the mean and variace of the spread and then using them in the equation. Although this does...
hi, this is what ive got so far and what i'm wanting to do is add a char to the end(and eventually the beginning) of the string but i can't seem to get it to work, do you think ive got the right idea
using namespace std;
using namespace PC3762...
So far i've managed to draw a sort of diamond structure but i want to put spheres on some of the connecting vertices, put figuring out the angles and distances is quite tough, i was wondering whether there was any way of moving a sphere along a connecting vertex line directly.
Any one any...
I've just completed an experiment using a laser to excite electons and hole in a germanium sample, and i want to fit a curve to some of the dat i've collected n origin, but i need to set up some initial parameters and i don't know how to work out what the origional number of injected holes...
