Matlab functions related to the page "introduction"
two_waves :
This function plot 2 wave in relative phase and their sum
Type in the command window:
two_waves(angle) The function argument: angel - the relative phase in degrees
Matlab functions related to the page "bragg scattering":
scanning_angels_func
This function scans angles for selected bragg plane
Type in the command window:
scanning_angles_func(h,f,d_teta,final_teta) The function arguments: h,f - components of G vector (for G=(1,2) : h=1 , f=2)
d_teta - the intervals between each angle (in degrees)
Example: if you want to see visualization of direction G=(1,1) from 10o to 80o
in intervals of 10o write in command window :
scanning_angels_func(1,1,10,10,80)
I_teta_graph_func :
This function plots graph of I vs. θ
Type in the command window:
I_teta_graph_func(d,λ) the function arguments: d - the distance between two bragg planes
λ - the wavelenght of the diffracting wave
Example: if you want to see plot of direction d=3 and λ=2 write in command window :
I_teta_graph_func(3,2)
Matlab functions related to the page "ewald construction"
ewald:
This function scans Bragg planes for different wave numbers k
Type in the command window:
ewald(k) The function argument: k- the wave number (k=2*π/λ)
Example: if you want to see visualization of scanning G vectors for k=5 type in the command window :
ewald(5)
All the programs are functions in matlab so in order to operate them you need to:
Windows:
open the zip file in yours matlab work directory
write in the matlab command window the appropriate function with the right arguments
UNIX:
donwload the 9 files to your matlab work directory
write in the matlab command window the appropriate function with the right arguments
