Hi Fred,
here's an example. This was tested in "Explore".
The table handle 'th' was used in this example.
UM
//-----------------------------------------------------------------
// HOW TO FILL AN AFL ARRAY WITH VALUES FROM A TABLE:
// define the array which you would like to use
// this sets up an "array" by a copy of the "C" array
myArray = C;
// initialize all elements of myArray to 0 (or use -1e10 for "null" data)
for (i = 0; i < BarCount; i++)
myArray[i] = 0;
// all arrrays in AFL have a fixed number of elements (BarCount)
// so we may fill only that much elements!
// calculate how much maximally can be retrieved
// from the table AND filled in the array
nMax = TableGetRowCount(th);
if (nMax > BarCount)
nMax = BarCount;
// finally fill the array from table1's column0 cells
for (i = 0; i < nMax; i++)
{
myArray[i] = TableDataGet(i, 0, th); // col 0 was defined as of type float
//...
}
// the first nMax elements of myArray were filled from the table
// for simplicity we are displaying the last index filled and its value
// in the results tab:
AddColumn(nMax - 1, "lastFilledElemIndex", 1.0); // remember ZERO based...
AddColumn(myArray[nMax - 1], "lastFilledElemValue", 1.3);
//...
