A 3D spreadsheet based on intensional logic

A three-dimensional spreadsheet design based on intensional logic is proposed. Intensional logic is concerned with assertions and other expressions whose meaning depends on an implicit context. The intensional spreadsheet is a declarative spreadsheet with a simple formal semantics called intensional semantics. It is expected to be suitable for a wide range of applications and for various users, including those who have had conventional programming experience. As an example of using the intensional 3-D spreadsheet, the formalization of a systolic algorithm for matrix multiplication is considered.<
