Re: Is existing a function in ncl who do product pf twomatrix (Aij*Bij)?

Hi Rolande,

The * operator does exactly what you want. E.g.

ncl 0> a=(/(/1,2/),(/3,4/)/)
ncl 1> write_matrix(a*a,"2i5",False)
  
    1 4
    9 16

ncl 2>

If you want a matrix multiplication you would need the # operator. E.g.

ncl 2> write_matrix(a#a,"2i5",False)

  
    7 10
   15 22
  
ncl 3>

Hope this helps,
Oli
