Curve Fitting – Trajectory of Projectile. The excel file, ProjectileData, has three columns of data: time, distance, and height. Import each of these columns into MATLAB using either xlsread or the Import Data tool. The variable distance represents measurements of the x-position (horizontal position) of the projectile over time and the ...

SI Fig. 1 The pre-edge background of the carbon K-edge of a polycrystalline diamond (PCD) composite (EELS data from Ref. 23) was fitted using a one-term exponential function of the form f x =a e bx . in the EELS_fitting.m MATLAB script.. Several fitting windows were chosen below (i) eV, from 155.5-200 eV to 155.5-280 eV, and plotted in a rainbow of colours to visually aid finding the best fit.

Curve Fitting with MATLAB. Curve fitting is a useful tool for representing a data set in a linear or quadratic fashion. MATLAB has two functions, polyfit and polyval, which can quickly and easily fit a polynimial to a set of data points. A first order polynomial is the linear equation that best fits the data. A polynomial can also be used to ...
