Two matrices are considered to be equal if they have the same value in every position. In other words, matrices A and B are equal if and -only if (∀i,j |i ∈ {0, 1, . . . , m − 2, m − 1}, j ∈ {0, 1, . . . , n − 2, n − 1}) ai,j = bi,j . ∀ is a common shorthand for -“for all,” so ∀i,j means “for every value of i and j.” ∈ is a common shorthand for “in”. +only if + +![alt text](images/matrix_equal_definition.png "matrix equal definition") + +∀ is a common shorthand for “for all,” so ∀i,j means “for every value of i and j.” ∈ is a common shorthand for “in”. Since a matrix has two dimensions, you will need to implement num rows() and num cols() which return the number of rows and the number of columns in the matrix respectively.
