**MATRIXSYMMETRIC (GeneratedMatrix,About)**

- is any matrix.

## Description

- This function shows the symmetric value of the given matrix.
- In , is any matrix.
- A matrix is said to be symmetric if .
- is the transpose of the matrix A.
- Normally equal matrices have equal dimensions, only square matrices can be symmetric.
- But using this function we can get the symmetric matrix even non square matrix also.
- Consider the matrix .
- So Symmetric matrix entries are .
- The properties of symmetric matrices are:

1. Every square diagonal matrix is symmetric, since all off-diagonal entries are zero. 2. Similarly, each diagonal element of a skew-symmetric matrix must be zero, since each is its own negative. 3. Hermitian matrices are a useful generalization of symmetric matrices for complex matrices.
