I need to give an array input to the transfer function block in simulink.

I got the following error:

Error in port widths or dimensions. Invalid dimension has been specified for input port 1 of <Model_Name>\Transfer_fcn'.

Component:Simulink | Category:Model error

Is there any possibility of getting a [1x20] array as output for this transfer function block.

if not, is there an alternative solution to this.

I don't remember that the Transfer Function block works as a MISO system.

If you think that all 20 inputs are fed into the same transfer function

, might as well duplicate additional 19 TF blocks and obtain the individul outputs separately.

You can apply the Superposition principle later if you want, by using an Add block.
