# Find Trace and Normal of Matrix C Program

## C Program To Find Trace and Normal of Matrix

Learn How To Find Trace and Normal of Matrix in C Programming Language. The **math.h** header files includes the definitions for **sqrt()** method.

#### What is a Trace?

A Trace calculated by adding up the Main Diagonal Elements of the Matrix. The Main Diagonal Elements are the ones that occur from Top Left of Matrix Down To Bottom Right Corner.

#### What is a Normal?

A Normal is the Square Root of all the Elements in the Trace of a Matrix.
