i am getting the following error when i execute newpr function

 Error using ==> minmax at 43
Argument has illegal type.

Error in ==> network.subsasgn>setInputExampleInput at 909 range = minmax(p);

Error in ==> network.subsasgn at 96 [net,err] = setInputExampleInput(net,i,exampleInput);

Error in ==> newff>new_5p1 at 144 net.inputs{1}.exampleInput = p;

Error in ==> newff at 89 net = new_5p1(varargin{:});

Error in ==> newpr at 67 net = newff(varargin{:});

Error in ==> menu_train_Callback at 13 net=newpr(t.inputvector,t.Targetvector,50); % 100 number of neurons ________________________________________________________________ but my actual code is

t=load('neural_data');

    display('inside class name');
    % Initialise new pattern recognise network
    net=newpr(t.inputvector,t.Targetvector,50);

Try running one of the examples in the documentation that use NEWPR - do you still see the same error?
