Hi,I got the code below which is to build how many peak I one based on the how many row I chose and I have attached the file for element to be put in multidimensional array and also the result I got:
% creating a multidimensional array
files = dir('*txt') ; % you are in the folder with text files
N = length(files) ;
names = {files(:).name}' ;
iwant = cell(N,1) ;
for i = 1:N
iwant{i} = importdata(files(i).name) ;
end
A = input('Please enter an element in form of iwant{i}:');
% find the number of samples
n = length (A(:,1));
% step change for the wavelength
step = 0.02;
% wavelength which is at the centre
p = A(:,1);
% to make new wavelength for each of wavelength in the samples
for j=1:n
new_wavelength(j,:) = p(j)-step*10:step:p(j)+step*10;
end
format shortG
j = input('Please input the row:');
i = input('Please input number for element:');
Delta_lambda=0.2;
int_fact= 0.00001.*iwant{i}(j,2);
denominator = Delta_lambda/2; % this is a constant
K=21; % the upper limit of the loop magic number
numerator = new_wavelength(j,11)-new_wavelength(j,1:K); % vectorize to have 21 elements
Peak_1(j,:) =(int_fact.*1./(1+(numerator/denominator).^2));
plot(new_wavelength(j,:).',Peak_1.','g')

But, it seem that all the peak is not connected. If possible could someone fix this problem? I been trying it for a few days but i kind of come to a death end. Hahaha. Thanks!
