## What is lookup table in Simulink?

A lookup table block uses an array of data to map input values to output values, approximating a mathematical function. Given input values, Simulink performs a “lookup” operation to retrieve the corresponding output values from the table.

**How do you create a table in Simulink?**

### How do I edit a lookup table in Simulink?

You can edit a lookup table using: Lookup Table Editor….To edit a lookup table directly in a block:

- Open the subsystem that contains the lookup table block.
- Open the lookup table block dialog box.
- In the Table and Breakpoints tab, edit the Table data and relevant Breakpoints parameters as needed.

**How do you create a lookup table in MATLAB?**

Specify breakpoint data sets and table data for lookup table blocks. Use the Lookup Table Editor plots to visualize data in the spreadsheet. Import data into a lookup table using copy and paste. Generate a report of one or more lookup tables in a model.

## How do you create a lookup table for a sine wave in Matlab?

**What are two kinds of lookup functions?**

There are two forms of Lookup: Vector and Array. The vector form of the LOOKUP function will search one row or one column of data for a specified value and then get the data from the same position in another row or column.

### How many types of lookup are there?

two forms

There are two forms of Lookup: Vector and Array. The vector form of the LOOKUP function will search one row or one column of data for a specified value and then get the data from the same position in another row or column.

**What is a lookup table in database with example?**

A lookup table is normally a table that acts as a “master list” for something and you use it to look up a business key value (like “Make”) in exachange for it’s identifier (like the id column) for use in some other table’s foreign key column.
