MULTIDIMENSIONAL ARRAYS IN C AND C++ Scientific programming requires the use of multidimensional arrays for almost everything. The need arises naturally  because very few nontrivial systems admit useful one-dimensional descriptions. Solving multidimensional PDE  systems requires scalar, vector, or even tensor fields to be tabulated at discretized grid locations. That means that in 3  space dimensions, 4d or even 5d arrays may be needed. Some examples of such systems are electrodynamics  simulations, fluid dynamics, and general relativistic calculations. When the problem domain is discretized using a  structured mesh where zones are topologically cubes, we refer to the grid as logically cartesian. Language support for logically cartesian grids is provided natively in Fortran, which has helped make it the industry  standard for science and engineering computing. C and C++, although they do not provide a native syntax for

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
