QUES7 MATRIX

C LANGUAGE BOOK

lets take an example.
In matrix.multiplication.

we have the matrix

first matrix have m row and n column
second matrix have n row and p column
when we multiply
third matrix should have m row and p column
((first matrix)m*n )*((second matrix)n*p )
n gets cancel out.

transpose

1 2 3
4 2 1
5 2 1

the transpose of this matrix is
1 4 5
2 2 2
3 1 1
