Data Definition

How defining data in MATLAB Function blocks differs from defining data for MATLAB® code

MATLAB variables can change their properties at run-time. The same variable can hold a value of any class, size, or complexity.

The MATLAB Function block must determine variable types at compile-time. Control how data is represented and how memory is allocated by how you design your MATLAB Function block code. Follow the described guidelines to allow the block to determine the types of variables when compiling the block or generating code from the block.
