What kind of metering divides the viewfinder into several sections, usually three or four, and analyzes them separately?

Matrix Metering

Matrix Metering or Evaluative Metering mode is the default metering mode on most DSLRs. It works by dividing the entire frame into multiple “zones”, which are then all analysed on individual basis for light and dark tones.

There are three main metering modes: Center-weighted average metering; spot and partial metering; and evaluative, pattern, or matrix metering. On modern digital cameras, you can choose between them. The process varies by manufacturer and camera, so look up your manual if you want to switch modes.
