How can I deploy matlab-generated neural network function? error using mapminmax_apply

We're using the genFunction to output the neural network classifier. We're trying to deploy the classifier on new input data - which has the same format (4 columns, many rows) as the original input data. Running the myNeuralNetworkFunction(NewData) gives the following error:

Undefined function 'mapminmax_apply' for input arguments of type 'double'.

Error in myNeuralNetworkFunctionv2 (line 35) xp1 = mapminmax_apply(x1,x1_step1_gain,x1_step1_xoffset,x1_step1_ymin);

Error in TestNeuralNetwork (line 15) a=myNeuralNetworkFunctionv2(NewData);

mapminmax_apply (generated by matlab) seems not to exist. We changed it to mapminmax.apply and got the following error message:

Error using apply Too many input arguments.

Error in myNeuralNetworkFunctionv2 (line 35) xp1 = mapminmax.apply(x1,x1_step1_gain,x1_step1_xoffset,x1_step1_ymin);

Error in TestNeuralNetwork (line 15) a=myNeuralNetworkFunctionv2(NewData);

Any help would be greatly appreciated
