MATRIXDETERMINANT (a)
- is any square matrix.
Description
- This function is calculating the determinant of the given matrix.
- In , is any square matrix.
- The determinant of a matrix is a special number that can be calculated from a square matrix.
- The determinant of a matrix is denoted by or .
- Let be 2x2 matrix with the elements
- Then , where all are real numbers.
- Let be the 3x3 matrix with the elements
Then :
- Let be a square matrix of order . Write ,
- Where is the entry on the row and column and to & to .
- For any and , set (called the co-factors), then the general formula for determinant of the matrix is,
, for any fixed . Also, for any fixed .
