Why is the output of the Simulink 'Bitwise Operator' a matrix (CompiledPortDimension)

Why is the output of the Simulink 'Bitwise Operator' a matrix (CompiledPortDimension)?

Which other blocks behave the same way?

[Kaustubha Govind]

What are the dimensions of the input(s) to the block in your model?

[Ernst]

Independent of whether the input is scalar or a vector the CompiledPortDimension is something like

2 x x (for scalar input 2 1 1)

Answer 1

[Kaustubha Govind]

It looks like the 'Bit Mask' parameter on the block may be a non-scalar in your block, which is why the output is a matrix even when the input is scalar.

[Ernst]

back to my problem: Input to the bitwise block is a vector with 4 uint16 (number of input ports is 1)

no mask

bitwise And/Or/ ...

then I get CompiledPortDimension 2 1 1

how can I decide that the outport signal is no matrix signal?

[Kaustubha Govind]

Ah! I think you may not be interpreting the CompiledPortDimension correctly - from my understanding, the first digit represent the number of dimensions, and the following digits represent the length of each dimension. So essentially, your output is a signal with dimensions 1x1 (ie. 2D signal). Does that make sense? For example, if the output were a mxnxp signal, CompiledPortDimension would be [3 m n p].
