[ncl-talk] average for two variables in ncl

[Dennis Shea]

When you get this type of error, you can debug by adding the following
*before* the statement that causes the error.

  printVarSummary(dailyT2avg(ifil,:,:))

  test_0 = dim_max_n(temp,0)
  printVarSummary(test_0)

  test_1  = (dim_max_n_Wrap(temp,0)+dim_min_n_Wrap(temp,0))/2.0
  printVarSummary(test_1)

Look at the dimension sizes

dailyT2avg(ifil,:,:) = (dim_max_n_Wrap(temp,0)+dim_min_n_Wrap(temp,0))/2.0

===
Further you gain nothing by using the _Wrap versions of the code. The
computations eliminate meta data.

dailyT2avg(ifil,:,:) = (dim_max_n_Wrap(temp,0)+dim_min_n_Wrap(temp,0))/2.0

===

I suggest

    tavg = (dim_max_n(temp,0) + dim_min_n(temp,0))/2.0
    printVarSummary(tavg)   ' look at dimensionality
