Similarly to formula attributes, matrices (Formula attributes) can be defined as formulas. Using a combination of matrix and vector expressions, you can define a term that is automatically updated when changes are made to matrix data or zone attributes. This way, the matrix is always displayed with its current values. The data in formula matrices is only readable (User Manual: Creating a matrix calculated from a formula).
