👉 In mathematics, a reshearer is an operator that acts on a vector space to create a new space. In other words, it's like creating a new vector space by taking two existing vectors and applying a special operation to them. Reshearings are often used in physics and engineering for solving partial differential equations or for manipulating certain types of matrices. For example, consider the vector space of all 2x2 matrices over a field F (like the real numbers or complex numbers). A
