Simulink with ROS : For loop for array of sensor_msgs/Image

Input: array of ROS sensor_msgs/Image (sensor_msgs/Image [])

Output: array of arrays/images (Images [])

I am trying to convert sensor_msgs/Image[] to Image array. But I can not use ReadImage block inside For each subsystem loop.

Hey Hassan,

I'm not sure how to do it inside standard Simulink blocks, but a workaround may be to pass the Image message array (or the message containing that array) into a MATLAB function block, and looping through the Image messages with readImage inside of there. Might be simpler than trying to manipulate the output array in a for loop in Simulink?

I tried this already but simulink does not run with readImage inside matlab function block which was the source of the problem. As a workaround, I tried to do it in simulink
