I am getting the error: ???
Undefined function or method 'sliderK_Callback' for input arguments of type 'double'.
Error in ==> Slider_nFlake at 28 sliderK_Callback(0,0);
The code is as follows:
function Slider_nFlake
%%Crea la figura
figura1 = figure ;
%%Create axes
graph = axes('LineWidth',1.5,'Position',[0.15 0.10 0.65 0.65]);
%%Create controls
% Sliders
sliderD = uicontrol('Style', 'slider', 'String', 'thickness',...
'Position', [20 370 200 20],'Callback',{@sliderD_Callback},...
'Min',1,'Max',10,'SliderStep',[0.001 0.001],'Value',3.0);
SliderDtext= uicontrol('Style', 'text','position',[20 350 200 20],'string','nFlakeRe');
textD = uicontrol('Style','text','Position', [20 390 100 20]);
sliderK = uicontrol('Style', 'slider', 'String', 'thickness',...
'Position', [230 370 200 20],'Callback',{@sliderK_Callback},...
'Min',0,'Max',10,'SliderStep',[0.001 0.001],'Value',0.0);
SliderKtext= uicontrol('Style', 'text','position',[230 350 200 20],'string','nFlakeIm');
textK = uicontrol('Style','text','Position', [230 390 100 20]);
sliderD_Callback(0,0);
sliderK_Callback(0,0);
% update slider value
%%Callback
function sliderD_Callback(source,eventdata)
D = get(sliderD,'Value');
set(textD,'String',D) ;
K = get(sliderK,'Value');
set(textK,'String',K) ;
[dd,cc]=contrast2(D,K) ;
hold off ;
plot(dd,cc) ;
end
end
Please could you actually tell me what Im doing wrong? I am trying to have a slider that when changed, gives the values to two variables D and K and put them into a function which I have in a different .m document:
function [dd,cc]=contrast2(nflakere,nflakeim)
lambda0=500;
nair=1;
nflake=nflakere+1i*nflakeim;
nSi=2+1i*0.06
dSiO2=285;
%loop
i=1;
for dflake=0:0.1:35
mSiO2=Sij(nair,nSiO2(lambda0))*Pj(nSiO2(lambda0),dSiO2,lambda0)*Sij(nSiO2(lambda0),nSi);
mflake= Sij(nair,nflake)*Pj(nflake,dflake,lambda0)...
*Sij(nflake,nSiO2(lambda0))*Pj(nSiO2(lambda0),dSiO2,lambda0)*Sij(nSiO2(lambda0),nSi);
%bare silicon oxide reflection coefficient
rSiO2=abs(mSiO2(2,1)/mSiO2(1,1))^2;
%flake reflection coefficient
rflake=abs(mflake(2,1)/mflake(1,1))^2;
%Contrast
C(i)=(rflake-rSiO2)/(rflake+rSiO2);
dflake2(i)=dflake;
i=i+1;
dd=dflake2;
cc=C;
end
As you can see dd and cc are the two variables I'm using in the slider_nflake.m and the D and K values obtained are used to obtain nFlake which consists of a nFlakeRe and nFlakeIm part (those values I would like to obtain when changing the slider). Please could someone help me!!! Thanks in advance

Your code shows you defining a nested function sliderD_Callback but there is no definition shown for any function sliderK_Callback, which you reference twice in your code.
