Matrix Coding

 Matrix Coding

Matrix coding reasoning is a type of logical reasoning which is used for doing various coding decoding problems. In Matrix coding two digits are used for representing English alphabets.

In matrix coding reasoning, rows and columns are used for representing digits.  Basically two types of matrices are used in matrix coding such as matrix I and matrix II. Digits in matrix coding are represented by respective rows and columns. Matrix I consist of 5 columns and 5 rows and they are used for representing digits. Rows and columns are marked as 0 to 4. Each row and column consists of five letters but their order was different in case of matrix coding. Five columns and rows exist in another matrix known as matrix II and elements in matrix II are marked from 5 to 9.
