MDETERM (Matrix) MDETERM (Matrix)
Matrix
The numbers of the matrix. This two-dimensional array must have a size that is equal to the sizes of its constituent arrays, with no blank values. In other words, it must be square.
Returns
Number Number
The matrix determinant of the given matrix.
Returns the matrix determinant of the given matrix. Matrices must be written differently compared to most spreadsheets. For instance, =MDETERM({ 3, 5; 1, 2 }) (written =MDETERM({ 3; 5\ 1; 2 }) if decimal commas are used instead of decimal points) should be written as MDETERM ({{ 3, 5 }, { 1, 2 }}) MDETERM ({{ 3; 5 }; { 1; 2 }}).
Example
MDETERM ({{ 3, 5 }, { 1, 2 }})
MDETERM ({{ 3; 5 }; { 1; 2 }})
Returns the matrix determinant, 1.
