x
Key x of function Evaluate in Timed Real To Real Functionrefers to the two-dimensional array of numerical tuplets, on which the referenced function must be repeatedly evaluated.
Each row corresponds to one tuplet and should contain at least K numbers, where K is the number of real variables expected by the caller function in addition to the always required first date variable which is supplied separately through the key Date
Look at the function description Timed Real To Real Function for details on the input and output variables.
For example, if the function is defined for certain values of its input date variable to call the bivariate normal distribution function Normal 2D Fn which has K = 2, it will expect a range with at least 2 columns, where the first two cells in each row supply the two input variables for each function valuation, while any extra columns are ignored.
If the input range consists of R rows and K columns, then the output is a vertically oriented array that extends over R rows and N columns, where N is the dimensionality of the function output.
