With regard to boost::multi_array:
Please, will somebody explain the difference between a View and a Subarray? I have read both the user and reference documentation, and can't find anything that indicates to me when you would use one over the other. So far as I can tell, they are essentially identical in purpose.
Views and Subarrays are very similar, that is true, but they are not quite identical. Subarrays are specifically the return type of operator[](index). When you index into a model of the MultiArray concept, you will get a subarray back. Views, on the other hand are, as the name suggests, for taking more generalized views of an array, for example a slice along some dimensions. As such, a view can look at a portion of a multi_array the same way that a subarray can, but the subarray is more specialized for its purpose. HTH, ron
