Lookup table (map)

Signature

Lookup2D(map, inputX, inputY, interpolationMode)

Description

Calculates the output value for a given 2D Table (map) and given X and Y axes' values.

Result

The output value which is calculated from the data of map at the location given by inputX and inputY.

Arguments

 

map

The map data used for the calculation. It must consist of an array of X-axis' values, an array of Y-axis' values and a matrix of output values. The number of columns in the matrix must be the same as the number of elements in the X axis. The number of rows in the matrix must be the same as the number of elements in the Y axis. Only signals of type Map (e.g. from a CDF file) can be used. The values of the X and Y axes must be monotonic.

inputX

The X input value for which the output value is calculated.

inputY

The Y input value for which the output value is calculated.

interpolationMode

Specifies how the output value is calculated: If it is 0, constant interpolation is used. If it is 1, linear interpolation is used. If inputX or inputY are outside the range of the X- or Y-axis' values, constant interpolation is always used.
