I am unable to see a plot in my MATLAB function that I am calling through C# and COM in R2006b. The program seems to execute properly, but I do not see the plot that my MATLAB function creates.

This behavior can occur when your C# application terminates before the MATLAB plot stays on the screen long enough for you to see it. You need to keep the C# program running while it instantiates the MATLAB object and calls the plotting function.

Consult your C# documentation for methods to determine when the user has viewed the plot and is ready to quit your application.
