mdeterm function 1


Syntax

=MDETERM(array)


Arguments

  • array (required): An array of numbers. The array must have the same numbers of rows and columns. It can be provided as:
    • A cell range, for example, A1:C3;
    • An array constant, for example, {1,1,1;2,2,2;3,3,3}.

Return Value

The MDETERM function returns a numeric value.


Function Notes

  • MDETERM will return the #VALUE! error if:
    • Any of the cells in the array are empty or contain non-numeric values;
    • The array does not contain the same number of rows as the number of columns.
  • The following equation takes an example to show how the matrix determinant is calculated:
    MDETERM(A1:C3) = A1*(B2*C3-B3*C2) + A2*(B3*C1-B1*C3) + A3*(B1*C2-B2*C1)
    √ Note: For more information about the determinant, please view the Wikipedia Determinant Page.

Example

Supposing you have an array as below screenshot shown, to get its determinant, please copy or enter the formula below in a blank cell, and press Enter to get the result:

=MDETERM({0.1,2,4;1,17,0;-2.5,3,-3})

Or, use cell references to make the formula dynamic:

=MDETERM(B3:D5)
