    Do u mean the differenciation operation??

    if yes try to do this way.

    do 10000 times.

    • calculate the change over the dependent variable in small intervals.

    • of independent variable.

    dz = dz+ (d2-d1 ) " accumulate values

    enddo.

    dz = dz/10000. " divide by the number of times.
