It's worth determining why your matricies have different 'typeof', and fixing this up-stream if appropriate -- are the values meant to be discrete and hence integer-valued, or continuous and hence numeric? I've made the change somewhat reluctantly, as it changes what the function does from 'combine' to 'coerce-and-combine'.
