In C, I've seen people do "multidimensional arrays" by A[n * i + j], with A a double[m * n], rather than by arrays of arrays. Especially if the array is being passed as a parameter, and the array's dimensions are given by other arguments, and the array is to be used with BLAS.

Is the compiler smart enough to do strength reduction and get rid of the multiply when indexing? FORTRAN compilers have been doing that for multidimensional arrays since 1954.
