Converting multidimensional arrays to pointers in c++ -

I have a program that looks like the following:

  double [4] [4] initial matrix; Double [4] [4] Inverted Matrix; Initialize (startMatrix) // This introduces the information I want in the beginning  

Now I want to calculate the inverse of startMatrix and want to put it in the inverse matrix. I have a library function for this purpose that has a prototype low:

  Zero matrix inversion (double ** a, int order, double ** b)  

Who takes the inverse of A and puts it in B The problem is that to give the function, I should know about double [4] [4] being converted to double form. I have tried to make it "clear path":

  matrix inversion (double **) start matrix, 4, (double **) inverted matrix))  

But it does not seem to work, is this really the right way to do it?

No, there is no right way to do this specifically. A double [4] [4] array is not convertible to a double ** indicator. These are two alternative, incompatible ways to implement 2D arrays. Some need to change: the structure of the array given as the interface's interface or argument.

The simplest way to do the latter, i.e. your current double [4] [4] function with a consistent array, pointing to the beginning of each line in each matrix double * [4] is to create a temporary "index" array

  double * startro [4] = {startmates [0], startmint [1], startmart [ 2], startmint [3]}; Double * Inversions RO [4] = {/ * Here's the same thing;  

and instead pass these "index" arrays

  Matrix Inversion (Startro, 4, Inverver Ross); After the  

function is over, you can forget about startrows and inverseRows arrays, because the result is placed in your original The inverse matrix array will be correct.
