Thursday, December 16, 2004"So... in an HTML analogy, your code now has a "style sheet" instead of you typing in the modifiers for every individual tag you use, every time you use it? (You load the main program once, then switch the parameters without re-performing the vast majority of the task?)"

Teaching may be a royal pain in the ass sometimes, but you're *very* good at it.
Just for the record. Now can you teach me all about the neural pathways, fasciculi, nuclei, topography and physiology? 'Cause my actual teachers apparently can't.
that's a pretty rad analogy for pointers. and yeah, that's exactly what matlab is doing. most "high-level" languages have done away with explicit pointers. java for example uses pointers nearly exclusively. in c referring to data by address is the special case, i.e. in c to use a pointer requires the use of an operator, '*'. the "special" case in java is reference by value, leadingly called a primitive.

an html analogy might not be that goofy. a hyperlink actually is a pointer. when you're composing a document and create a link, you simply put the address of the page in an anchor tag, exactly the same way in which you'd pass the address of the matrix to a matlab function or the location of the blackboard to a ta. the alternative to reference by address would be to include the content of that link inline with the rest of the first document's html. which would be a lot more typing. i'm stuck in kathmandu where a maoist strike has closed nearly everything down, so there's nothing to do but post nerdy shit on people's blogs and wait for my flight to australia on wednesday. :) jimmyk |
