# Add Matrix Lookups (Managed Package)

For the managed package runtime, a matrix lookup step calls a calculation matrix, supplying input to the matrix and returning its output.

![Managed Package app icon](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-xcloud-omnistudio_for_managed_packages-264-0-0-production-enus/aa2554ec-624a-4ee6-8da4-6435670e6e62/resources-global/_corporate/images/managedpackageicon.png) This information is for Omnistudio for Managed Packages. For Omnistudio on standard runtime, see [Omnistudio Help](https://help.salesforce.com/s/articleView?id=xcloud.os_omnistudio_standard.htm&language=en_US).

1. In the Calculation Steps area, click **Add Step**.
2. Select **Matrix Lookup**.
3. In the **Matrix Name** field, enter the name of the calculation matrix.
    
    After you select the calculation matrix, the calculation step displays the matrix inputs and outputs. The system adds all columns to the Variables section. Vlocity grays out variables it adds for matrix lookups, so you can't accidentally modify or delete them.
    
    A link to the calculation matrix also appears on the calculation step.
4. To make this calculation step conditional, select **Conditional Step**.
    
    Enter the condition that will invoke this matrix lookup.
5. To include the matrix lookup output in the calculation output data, select **Include in Calculation Output**.
6. Click **Save Calculation Procedure**.
