i have code in gui and if condition does's work why? please help me

M = xlsread('D:\traindata.xls')
N = xlsread('D:\testdata1.xls')
Training_set = M(1:100,2:10)
%specify training set
Target_set = M(1:100,10)
%specify target set
Testing_set = N(1,2:10)
%index=N(:,10)==0002-1;
%specify Testing set
Testing_Target_Set = N(1,11)
%specify Testing set,Target
%X = mapstd(Training_set');
%Y = mapstd(Target_set');
mynetwork = newrb(Training_set',Target_set',0,0.5,100,25)
%newrb(P,T,goal,spread,MN,DF) takes two of these arguments,
%PR x Q matrix of Q input vectors
%TS x Q matrix of Q target class vectors
%goalMean squared error goal (default = 0.0
%spreadSpread of radial basis functions (default = 1.0
%MNMaximum number of neurons (default is Q)
%DFNumber of neurons to add between displays (default = 25)
mynetwork.trainFcn='trainlm';
mynetwork.trainparam.min_grad=0.00000001;
mynetwork.trainparam.epochs=100;
mynetwork.trainparam.ir=0,4;
mynetwork.trainparam.max_fail=20;
%save mynetwork
D=sim(mynetwork,Testing_set')
%simulate network
xlswrite('D:\testdata1.xls',D',2)
%xlswrite(filename, M, sheet) writes matrix M to the specified worksheet sheet in the file filename
if D==1
     L='Not Existing'
    set(handles.text3,'String',L);
    
 elseif D==2
     K='Existing'
    set(handles.text3,'String',K);  
 
end

Answer 1

[Walter Roberson]

radial basis networks are function approximations, and will seldom return exact integers -- especially since we do not know that the training targets are 1 or 2.

You should put in a breakpoint after simulation and look closely at the output D to see if it is exactly 1 or 2.

I need the correct syntax for if conditions in this code

[Walter Roberson]

Put in a breakpoint in the code, and examine to see what values are present for D. Look carefully, including looking at

D - floor(D)

to detect values that display like integers but are slightly different than an integer.

Your should attach your data files so other people can test.
