Applying Matrix Multiplication to 2D Computer Graphics

February 7, 2021greg.mayer

Linear transformations are often used in computer graphics to simulate the motion of an object. They can be computed using a matrix-vector product of the form $$T(\vec x) = A\vec x$$ where $\vec x$ is a vector that represents a…Continue readingApplying Matrix Multiplication to 2D Computer Graphics

The Leontif Input-Output Model

January 29, 2021October 10, 2021greg.mayer

An input–output model are used in economics to model the inter-dependencies between different sectors of an economy. Wassily Leontief (1906–1999) is credited with developing the type of analysis that we explore in this chapter. His work on this model earned…Continue readingThe Leontif Input-Output Model
