what is the key element of skill matrix
Reduced matrix is a matrix where the elements of the matrix is reduced by eliminating the elements in the row which its aim is to make an identity matrix.
They are the number in the matrix.
A sparse matrix is a matrix in which most of the elements are zero.
No. A scalar matrix is a diagonal matrix whose main diagonal elements are the same. Only if the diagonal elements are all 1 is it an identity matrix.

Elements.
matrix
A matrix that have one or more elements with value zero.
Zero Matrix When all elements of a matrix are zero than the matrix is called zero matrix. Example: A=|0 0 0|
To find the inverse of a matrix using the Casio fx-991MS calculator, first, enter the matrix mode by pressing the "MODE" button until you reach the matrix option. Then, input the dimensions of the matrix (e.g., 2 for a 2x2 matrix). After entering the matrix elements, press the "SHIFT" button followed by the "MATRIX" key (which is also labeled with an inverse symbol). Finally, select the matrix you want to invert, and the calculator will display the inverse matrix.
Lower-triangular Matrix A square matrix A whose elements aij=0 for i
It will either be a 1*23 row matrix or a 23*1 column matrix.
