n dimensional quadratic #61

Closed chelseas closed 2 years ago

Is this paragraph referring to an n-dimensional quadratic? Because this detail seems important and it is not currently specified.

Is this paragraph referring to an n-dimensional quadratic?

One cannot have n mutually conjugate directions in a space smaller than n dimensions, so yes. The book uses n to mean the number of design variables.

chelseas commented 2 years ago

Ok so are you going to clarify? I'm not sure the average student has it top of mind that you need to have a space of at least n dimensions. It's also a simple fix to say "an n-dimensional quadratic function" or "a quadratic function in n dimensions"

chelseas commented 2 years ago

It's already on a new line.

chelseas commented 2 years ago

I feel like sometimes you can be a bit dismissive of my suggestions.

tawheeler commented 2 years ago

Okay, clearly you feel strongly about this issue. I will change "Recall that n line searches along mutually conjugate directions will optimize a quadratic function." to "Recall that n line searches along mutually conjugate directions will optimize an n-dimensional quadratic function."
