Math and Trignometric - MDETERM Function

Description

The MDETERM function returns the matrix determinant of an array.

Syntax

MDETERM (array)

Arguments

Argument Description Required/Optional
Array A numeric array with an equal number of rows and columns. Required

Notes

  • Array can be given as a cell range, for example, A1:C3; as an array constant, such as {1,2,3;4,5,6;7,8,9}; or as a name to either of these

  • The matrix determinant is a number derived from the values in array. For a threerow, three-column array, A1:C3, the determinant is defined as −

MDETERM (A1:C3) =A1*(B2*C3-B3*C2) + A2*(B3*C1-B1*C3) + A3*(B1*C2-B2*C1)

  • Matrix determinants are generally used for solving systems of mathematical equations that involve several variables

  • MDETERM is calculated with an accuracy of approximately 16 digits, which may lead to a small numeric error when the calculation is not complete

  • MDETERM returns the #VALUE! error when

    • Any of the cells in the array is empty or contains non-numeric values

    • Array does not have an equal number of rows and columns

Applicability

Excel 2007, Excel 2010, Excel 2013, Excel 2016
