Excel Matrix Functions: Overview Guide

by

In this post, we’ll explore Excel matrix functions in detail, helping you understand how to use them for matrix operations.

Below, you’ll find an overview of matrix related functions along with links to more detailed guides for each one.

Essential Matrix Functions in Excel

Excel offers several matrix functions that help with complex calculations. These functions are useful for tasks like multiplying matrices, finding inverses, or calculating determinants. The list of matrix related functions in Excel:

  1. MMULT: Matrix Multiplication
    The MDETERM function calculates the determinant of a square matrix. Determinants are useful in linear algebra, especially for understanding the properties of matrices.
  2. MINVERSE: Inverse of a Matrix
    The MINVERSE function computes the inverse of a matrix, a key operation in solving systems of equations.
  3. TRANSPOSE: Reorganize Data
    TRANSPOSE is a handy function for changing the orientation of a matrix, turning rows into columns and vice versa.
  4. MDETERM: Determinant of a Matrix
    The MDETERM function calculates the determinant of a square matrix. Determinants are useful in linear algebra, especially for understanding the properties of matrices.
  5. MUNIT: Unit Matrix
    The MUNIT function in Excel returns a unit matrix (aka identity matrix) of a specified size.
  6. Addition and Subtraction:
    There is no direct matrix function for these operations. You can use simple math operators for matrix add and sub.

Matrix Functions Use Cases

Excel matrix functions are widely used in areas such as mathematical calculations, data analysis, and financial modeling. These functions allow you to perform operations on data sets, saving time when working with large and complex data tables. Common use cases for matrix functions include:

  • Engineering: Solving systems of equations and running simulations.
  • Linear Algebra: Find solutions to systems of equations.
  • Statistics: Use in regression analysis for calculating coefficients.
  • Financial Modeling: Performing calculations for investment portfolios and risk analysis.
