+	* Returns the index of the first truthy element in a double-precision complex floating-point strided array.

+	* ## Notes
+	*
+	* -   A complex number is truthy when at least one of its real or imaginary components is truthy.
+	* -   If unable to find a truthy element, the function returns `-1`.
+	* -   The function explicitly treats `NaN` values as falsy.
