Introduction To Matrix Functions
Learn what Excel matrix functions do, when to use them, and how MUNIT, MDETERM, MINVERSE, and MMULT fit together.
Mdeterm Function
Returns the determinant of a square numeric matrix. Use it to check whether a matrix can be inverted before moving on to MINVERSE.
Minverse Function
Returns the inverse of a square matrix. It is mainly used when you need to solve matrix equations or verify matrix relationships.
Mmult Function
Returns the matrix product of two arrays. It is useful for weighted scoring, matrix transformations, and matrix checks in Excel.
Munit Function
Returns an identity matrix for the size you specify. This is useful when you need a neutral matrix for testing or matrix setup.
Matrix functions in Excel enable array-level computations across entire rectangular grids without slow helper columns. Master identity matrix generation with MUNIT, determinant solvability checks with MDETERM, matrix inversion with MINVERSE, and matrix multiplication with MMULT.
Learn how dimension matching rules and modern dynamic array spilling allow you to model systems of linear equations, Markov chains, and multivariate portfolio transformations directly inside your spreadsheet.
