problem with signal dimension in If-else block

Hi all,

in my project i use a If-else block after a logical AND block. The AND port recieves two signal from input ports of dimension 8-Its produce a signal of same dimension redirect as incomming singal in If-else block.(see attached figure)

The error generated from Update diagram phase is : " _Error in port widths or dimensions. Output port 1 of 'model ' is a one dimensional vector with 8 elements."

Maybe it's due to how matlab manage the variable, It uses array or matrix. How can skip this problem ?

Thanks!!!! italic

Use Demux block to extract the array elements from output of AND block into 8 individual signal. Perform the logical operation between the signal as needed and pass the output to "If block".
