This is my code , im trying to develop an ANN model for solar radiation prediction , Im getting the error Dimensions of arrays being concatenated are not consistent. I dont know which line the error is help someone . Thanks in advance
G_T=xlsread(fileName, sheetName , 'B3:B39999');
M=xlsread(fileName, sheetName , 'AO3:AO39999');
D=xlsread(fileName, sheetName , 'AN3:AN39999');
H=xlsread(fileName, sheetName , 'A3:A39999');
G_T_Test=xlsread(fileName, sheetName , 'B40000:B44641');
M_Test=xlsread(fileName, sheetName , 'AO40000:AO44641');
D_Test=xlsread(fileName, sheetName , 'AN40000:AN44641');
H_Test=xlsread(fileName, sheetName , 'A40000:A44641');
%------------
inputs = [M,D,H];
I=inputs;
targets= [G_T];
T=targets;
%-------ann Model development and training
net = newff(I,T,5);
Y = sim(net,I);
net.trainParam.epochs = 100;
net = train(net,I,T);
%------------testing the developed model--------
test=[M_Test,D_Test,H_Test];
Test1=test;
G_Mi = sim(net,Test1);
G_M= G_Mi;
%-------------------
G_Tp=[ ];
for i=1:1:length(G_M)
G_Tp=[G_Tp ; G_M(i,1)];
end
G_Tp;
plot (G_T_Test)
hold on
plot(G_Tp,'red')
This is my code

Xlsread has become obselete. You should try readtable.
T = readtable(myfile) ;
From T you can pick any column, index you want. This makes your life more easy. You can straight away pick the data you want and you can avoid such errors like joining data.
