Isn't double[][] equivalent to **double?

Question

I\'m asking this because my program have two functions to multiply matrices, they multiply only 4x4 and 4x1 matrices. The headers are:

 double** mult4x1(doub         


        

Answer 1

Another difference is that you can not make double to point to any other memory address if you declare it as double[][] ( Something like final field )

But if you declare it as **double, then it can point to any memory location.
