Sort2DArray (Function)
The Sort2DArray function performs a linked sort of values in a two dimensional array, using the primary dimension as the key.
Syntax
Sort2DArray(PriceArray, Size1, Size2, HiLo)
Parameters

Type |
Description |
PriceArray |
Numeric Array |
Specifies the name of a numeric array containing values upon which the sort is performed. |
Size1 |
Numeric |
Sets the number of array elements (size) in the 1st dimension to be sorted. |
Size2 |
Numeric |
Sets the number of array elements (size) in the 2nd dimension to include in the sort. |
HiLo |
Numeric |
Sets the sort order. 1 = sort descending, -1 = sort ascending |
Returns (Double)
The order of values of the two-dimensional array specified in PriceArray are changed as the result of running Sort2DArray. The Sort2DArray function itself returns 1.
Remarks
This function is used to change the order of values in an array by sorting them in either ascending or descending order based on the HiLo input. The sort is performed using the elements of the 1st dimension as a key.
The value for the Size1 and Size2 input parameters should always be a whole number greater than 0 and is typically equal to the number of data elements in the array.
The Sort2DArray function only works with two-dimensional arrays. All array-based referencing begins with array element 1.
Example
Performs an ascending sort of the user declared two-dimensional array..
Array: myArray[30,4](0);
{… (assign values to array) }
Value1 = Sort2DArray(myArray, 30, 4, -1);
