Lookup table in microprocessor

WebLookup table blocks such as Cosine and Sine Use blocks from the Lookup Tables library to model nonlinearity. Lookup table blocks use arrays of data to map input values to output values, approximating mathematical functions. To approximate a function in N variables, use the n-D Lookup Table block: WebUse LOOKUP, one of the lookup and reference functions, when you need to look in a single row or column and find a value from the same position in a second row or column. For example, let's say you know the part number for an auto part, but you don't know the price. You can use the LOOKUP function to return the price in cell H2 when you enter ...
