## Matrix Tab

The **Matrix** tab allows you to have a global view on the assignment of sub-material groups (represented by numbers) and actions (within a step). It is especially recommended to use the **Matrix** tab in case you want to see the correlation between the sub-material groups and the steps and actions.

In this tab, you can collapse and expand Steps by selecting the arrow icon. If the State of the **Experiment Definition** is Created, you can also add Steps by selecting the :material-plus: icon. For more information, see [Step 5: Add Experiment Definition Step](../create_experiment_definition/#step-5-add-experiment-definition-step).

At each **Step**, it is also possible to Edit or Delete actions and the allocation of materials by selecting the **More** option in the **Matrix**.

!!! note
	To Edit or Delete, the State of the **Experiment Definition** must be Created.

By selecting any of the numbers, you have access to the following details on the right panel:

* **Experiment Definition**
* **Step**
* **Material Group**
* **Action**
