I have a curve here which I have to deconvolve it into many other curves with different peaks. The resault is this in another program:
That is I have to deconvolve one curve in 4 curves in Matlab! I want to do the same thing in Matlab but I failed!
clc
clear all
D398=importdata('J398.txt');
D398=flipud(D398); %its a spectrum from higher values to smaller!
X1=D398(:,1); Y1=D398(:,2);
[X,Y]=deconv(X1,Y1);
plot(X1,Y1)
hold on
plot(X,Y,'r')
set(gca, 'XDir','reverse')
grid on
But it is not correct! Is that possible to do this in Matlab ?

Hi, you may try 4 Gauss Function:
The results will be:
Root of Mean Square Error (RMSE): 451.21462729511
Sum of Squared Residual: 49066308.2123007
Correlation Coef. (R): 0.999771552934335
R-Square: 0.999543158056732
Adjusted R-Square: 0.999539319048805
Determination Coef. (DC): 0.999543158056733
