What do you mean by "summarize"? If for instance you want to sum along Y, just do   my_array.sum(axis=1)

hi, all

Say I have a three dimension array, X, Y, Z,  how can I condense into two dimensions: for example, compute 2-D array with (X, Z) and summarize along Y dimensions ... is it possible?

thanks
