How dictionary works
- Keys and values must have the same number of elements.
- String, numeric, logical, char, and cell collections are expanded into element lists.
Example
Create a dictionary
D = dictionary(["a" "b"], [1 2])Expected output:
D = dictionary objectUsing dictionary with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how dictionary changes the result.
Run a small dictionary example, explain the result, then change one input and compare the output.
