How to get max / min element from multiarray

Question

I am interested in a simple way to find the maximum / minimum element of a multi-level boost, an object of 3 indices in the following form:

int iDepth=10,iWidth=10,iHeight=10; boost::multi_array<GLfloat, 3> image(boost::extents[iDepth][iWidth][iHeight]); 

Answer 1

This should work:

 std::max_element( image.origin(), image.origin() + image.num_elements()); 

Answer 2

You tried something like:

 std::max_element( image.begin(), image.end());
