MDETERM function

MDETERM(matrix) MDETERM(matrix)

matrix — {{ Number }}

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

The matrix determinant of the given matrix.

Returns the matrix determinant of the given matrix. Matrices are written differently in Calcapp compared to most spreadsheets. For instance, =MDETERM({ 3, 5; 1, 2 }) (written =MDETERM({ 3; 5\ 1; 2 }) with decimal commas) is written as MDETERM({{ 3, 5 }, { 1, 2 }})MDETERM({{ 3; 5 }; { 1; 2 }}) in Calcapp.

Example

MDETERM({{ 3, 5 }, { 1, 2 }})MDETERM({{ 3; 5 }; { 1; 2 }})

Returns the matrix determinant, 1.
