concatenate arrays in structures
in [Matlab]

From: wwhipple Whipple on 2 Jun 2010 00:30 I have a series of four-level deep structures. The series contains 8-16 such elements, each ofwhich has thousands of level-four fields so some efficiency would be desirable. At the fifth level are two arrays. Each element of the series has the same fields to the fourth level and the same two array names at the fifth level. The arrays have different content and sizes. I wish to concatenate the arrays of the same name in the order that the elements of the series are named. The resulting arrays should be embedded in the same four-level structure and each array should be of size equal to the sum of the sizes of arrays of the same name. The resulting structure will be 8-16 GByte in size. cat, vertcat, and horzcat produce essentially a matrix of arrays in a structure, not single arrays.

First of all, try to create an arbitrary 8-16 Gbyte array on your computer ... if you succeed come back here. Jos
