hello guys,
i have a problem in my labview programs. how to process data in the past based from data in the present ?

i have a formula self-organizing maps

this formula is looking for D1, D1 is neuron index that will be searched for the smallest value.and the result are D1=2 ,D2=5, D3=17 from calculating with formula  .it means the smallest value is 2, "2" from weight [2 2] in file attached.

and then it will be in other formula

it mean [2 2] + 0.5 ( [1 1]-[2 2] ) = [1.5 1.5]

and the weight will be  [1.5 2 2 ] in matrix
                                          1.5 3 5

I would appreciate any input/help on solving this

thanks
