Description
Twodimensional Lookup table generates an output signal by interpolating based on a given data set and three input values: input values x, input values y, and input values z. The Input values x, the Input values y, and the Input values z properties must be strictly increasing or decreasing arrays.
 An example of equidistant distribution of input values would be: in_vec_x = [2, 1, 0, 1, 2];
 An example of nonequidistant distribution of input values would be: in_vec_x = [4, 0, 2, 3, 10]
The table output can be calculated using equidistant space method or nonequidistant (binary search) implementation method.
When the input vectors (Input values x, Input values y, and/or Input values z) have nonequidistant distribution and equidistant space method is selected, internal conversion from nonequidistant to equidistant distribution will be done. In this case, a warning will be displayed during compilation.
 If the extrapolation method is Clip, the value returned on the output will be the first value of the output vector, if the input value x and/or the input value y is less than the first set of values of input vectors. If the input value is greater than the last set of values of the input vector, the value returned on the output will be the last value of the output vector
 If the extrapolation method is linear, a line between the first or last values of output vector f(x,y) is traced, depending on whether the input values are less than the first or greater than the last values of the output vector. Linear extrapolation method returns the value of the generated line corresponding to the inputs.

Properties
 Input values x
 Type in the array of input values x used to calculate the output of the lookup table
 Input values y
 Type in the array of input values y used to calculate the output of the lookup table
 Input values z
 Type in the array of input values z used to calculate the output of the lookup table
 Output values f(x, y, z)

 Implementation method
 Choose the interpolation method used to calculate the output values when the input value is within the input array range.
 Extrapolation method
 Choose the extrapolation method used to calculate output values when the input value is outside of the input array range.
 Execution rate

Type in the desired signal processing execution rate. This value must be compatible with other signal processing components of the same circuit: the value must be a multiple of the fastest execution rate in the circuit. There can be up to four different execution rates, but they must all be multiple of the basic simulation timestep. To specify the execution rate, you can use either decimal (e.g. 0.001) or exponential values (e.g. 1e3) in seconds. Alternatively, you can type in â€˜inheritâ€™ in which case the component will be assigned execution rate based on the execution rate of the components it is receiving input from.
