Numpy modify array in place?

Question

I have the following code which is attempting to normalize the values of an m x n array (It will be used as input to a neural network, where m is t

Answer 1

def normalize(array, imin = -1, imax = 1):
    """I = Imin + (Imax-Imin)*(D-Dmin)/(Dmax-Dmin)"""

    dmin = array.min()
    dmax = array.max()


    array -= dmin;
    array *= (imax - imin)
    array /= (dmax-dmin)
    array += imin

    print array[0]
