Not enough input arguments in function called

Hello

My Code while running gives a basic error while calling the function.

Not enough input arguments.

Error in function (line 45) (very last line of my post)

train_data=load(TrainingData_File); test_data=load(TestingData_File);

I have tried my best to compare the arguments but it is not working out. Can anyone please check the code. I am attaching the data file and the inbuilt function that is being called. That being said as I am stuck I can't proceed to the next stages.

Thanks very very much in advance for your time and effort

data file code which calls the function

data_len= length(data)

train_length = round(data_len/2);

RawData=data;

nn=size(RawData,2);

for index=1:nn

NormData(:,index)=(RawData(:,index)-min(RawData(:,index)))./(max(RawData(:,index))-min(RawData(:,index)));

end

%%

%Preparing training data

Trn_inputn=NormData(1:train_length,1:nn-1);

Trn_outputn=NormData(1:train_length,nn);

Chk_inputn=NormData(train_length+1:end,1:nn-1); Chk_outputn=NormData(train_length+1:end,nn);

TrainingData_File =[Trn_outputn Trn_inputn];

TestingData_File = [Chk_outputn Chk_inputn];

%%

mean_training=mean(TrainingData_File)

mean_test=mean(TestingData_File)

std_training=std(TrainingData_File)

std_test=std(TestingData_File)

var_training=var(TrainingData_File)

var_test=var(TestingData_File)

%explanatory_var=[]

explanatory_var= [mean_training; mean_test; std_training; std_test; var_training; var_test]

%%

THE FUNCTION CALLED IS

function [TrainingTime, TestingTime, TrainingAccuracy, TestingAccuracy] = OSELM(TrainingData_File, TestingData_File, Elm_Type, nHiddenNeurons, ActivationFunction, N0, Block)

REGRESSION=0;

CLASSIFICATION=1;

%%%%%%%%%%% Load dataset. FOLLOWING IS LINE 45

train_data=load(TrainingData_File); test_data=load(TestingData_File);

Where are you calling the OSELM function? I suspect you forgot to enter the input arguments there.

[Walter Roberson]

it is confusing that TrainingData_File is intended to be character when used in the function but is numeric in the script .

also we do not know the filenames so we do not know if load() is returning numeric or struct . Numeric is implied in context which would require reading from aa text file; it is usually clearer to code one of the routines that deals with text files rather than the ambiguous load()
