A matrix is a rectangular array of numerical values. You can add or multiply two matrices to form a third matrix. You can multiply a matrix by a scalar, and you can transpose a matrix. Design an ADT that represents a matrix that has these and other operations. Extra credit will be awarded for very complex, well$-$thought$-$out designs and implementations. The ADT should have at least seven operations$/$methods$.$ a$)$ Describe the data. Identify at least two private data fields. b$)$ Identify the ADT$$s behaviors and write the behaviors on a CRC card. For example, in the ADT bag example, one behavior is to identify how many objects the bag contains.
