Dear Matlab friends,

I am trying to work with the following code (availabe in matlab help) in neural network ,

load house_dataset;
net = newff(houseInputs,houseTargets,20);
net=train(net,houseInputs,houseTargets);

It works perfectly, the same code modified as follows for my data set,

load st_inputs.dat;
load st_targets.dat;
inputs=st_inputs(1:1237,1);
targets=st_targets(1:1237,1);

net = newfit(inputs,targets,20);
net=train(net,inputs,targets);


it produce the following error

??? Error using ==> plus
Matrix dimensions must agree.

Error in ==> calcperf2 at 163
N{i,ts} = N{i,ts} + Z{k};

Error in ==> trainlm at 253
[perf,El,trainV.Y,Ac,N,Zb,Zi,Zl] =
calcperf2(net,X,trainV.Pd,trainV.Tl,trainV.Ai,Q,TS);

Error in ==> network.train at 216
[net,tr] = feval(net.trainFcn,net,tr,trainV,valV,testV);

Error in ==> netfit_stock at 10
net=train(net,stockinputs,stocktargets);

and also i am using newff instead of newfit. This line also produce the same error.
I can't understand this error.
Please help me.
