matrix with 2 rows and 1 column Simulink

Hello,

I am getting this error in Simulink..

Error in port widths or dimensions. The signal ... block must be a matrix signal of 2 rows and 1 columns.

Component:Simulink | Category:Model error

Error in port widths or dimensions. .. is a one dimensional vector with 2 elements.

But is a 2 rows and 1 columns matrix not equal to a one dimensional vector with 2 elements??

It is both 1x2? For example x = [1;1] (this is what I have input for example to get this error).

Cheers

Can you share the model so we can examine the problem?
