Structures

Definition and supported structure operations

You can define variables in MATLAB Function and MATLAB System blocks as structures.

Blocks

MATLAB Function	Include MATLAB code in models that generate embeddable C code
MATLAB System	Include System object in model

Functions

coder.cstructname Name C structure type in generated code
