The Embedded Coder^® Dictionary and Code Mapping Editor in R2018a let you assign default definitions, storage classes, and memory sections to entire classes of data such as inputs, outputs, and parameters. 

Unlike previous approaches of using custom storage classes specific to each data item, in 2018a, you can now specify default mappings for a wide range of Simulink^® data to generate code data. This approach saves time and effort, plus makes model upgrades easier. In addition, there are new autonaming options for specifying model-level source and header files.

This presentation is from Coder Summit Talks, which are live recordings of developers and engineers debuting their best MATLAB^® and Simulink Coder™  optimizations and examples at an annual technical interchange.
