error processing FNN

    i have a dataset and have have divided into 5 folds ,i have done coding for converting numerical values,but struck at this process,is there any coding to process else i have to use tool box,please help,struc here for nearly 6 months

    The FNN   consists of four layers, i.e., the input layer, the input membership
    function layer, the rule layer, and the output layer. The input membership
    function layer converts numerical values to categorical values. Each rule
    node is connected to all input membership function nodes and output
    nodes for this rule. Each rule node performs a product of its inputs. The
    input membership functions act as fuzzy weights between the input layer
    and the rule layer. Links between the rule layer, the output layer, and the
    input membership functions are adjusted during the learning process. In
    the output layer, each node receives inputs from all the rule nodes
    connected to this output node and produces the actual output of the
    network.
