MQL5 Question: unable to initialise a 2 dimensional array using existing array variables

[Varun Maithani]

Hi

Below is the code (for Script) i am trying to compile but i get error. I am not sure why i cant get this syntax to work.

enum SBP
  {
   SS = 0,

   MM = 1,
   
   WW = 2
  };
void OnStart()
  {
        double aa[5] = {1,2,3,4,5 };
        double bb[5] = {6,7,8,9,10 };
         double cc[5] = {11,12,13,14,15};
      
        double dd[3][5] = {aa, bb, cc};
        Print(" dd[WW][SS]  = ",dd[WW][SS]);
  }

Error is shown below:

'aa' - invalid array access     
'bb' - invalid array access     
'cc' - invalid array access

It is simply not the way you can deal with array in MQL5.

For what you want you should use matrices and vectors. See here https://www.mql5.com/en/docs/matrix
and study the examples there.

You can initialize N-dimensional arrays directly:

  double dd[3][5] =
  {
    {1,2,3,4,5},
    {6,7,8,9,10},
    {11,12,13,14,15}
  };

Thanks i will use that way then
