Standard Matrix

Principles

?

• A = [T($\vec{e_1}$), T($\vec{e_2}$), … T($\vec{e_n}$)]
• What you apply to points to produce a certain transformation

Domain and Co

• Domain is the number of columns
• Codomain is number of rows, as thats how many there were in output

Finding standard matrix of a transformation

• Take columns of identity matrix into transformation ?
  • Wherever they end up, the ouput vectors form the transformation matrix

Finding standard matrix of linear mapping

• Plug in standard basis vectors, combine them into matrix after
• 3.2 B20
