noted.
Multiple Arrays within a Block
All blocks support multiple vectors (arrays) as both outputs and inputs.
However, depending on exactly how the signals are connected and the
algorithm, loops might not be generated as expected. Generally speaking,
as long as multiple arrays are connected contiguously to the inputs of the
block, loops are possible. For example, examine the model in Figure 6-3
and the generated code in Example 6-6.
