Write your own code to perform matrix multiplication. Recall that to multiply two matrices, the inner dimensions must be the same. [A]_mn [B]_np = [C]_mp Every element in the resulting C matrix is Use Java. One interesting application of two-dimensional arrays is magic squares. A magic...
The NumPy library has many functions that can manipulate arrays and matrices. For example, the flatten function will convert a matrix to an array. Now, as it turns out, the SciPy matrix multiplication function is smart enough to infer what you intend if you multiply a matrix and an array ...
