Does like this ?

int k = 3;
float [] a = new float [k*n];
float [,] b = new float [k, n];

for (int i = 0; i < a.length; i++)
    b[i / n, i % n] = a[i];

  1. Allocate your new 2D array
  2. Allocate a new 1D array for each row in the 2D array
  3. Copy the old elements in your new array with a nested loop: column-by-column, row-by-row
