I have created one module i.e (Vehicle number plate recognition) in MatLab and the other module (vehicle management system) in C#, Now i want to integrate these. Help me kindly

What does integrate these actually mean?

What is it that you don't know how to do?

Have you looked at calling matlab from C# and Calling .Net libraries from matlab?

Integrate mean to combine 2 different modules in one project

The above works well (y) but the last one is to show image in axis?? Its not working, tell me in which format should i save image in array?
