I am having an issue with the interaction of the Matlab function block in the Simulink with my model block. Below you can also find the picture. I have created a Matlab function with three inputs and 1 output. Since in the MatLab function block, I have solved a differential equation, it has complex expressions in the form of for example.
This generates the output of complex data types from the function block. When passing this to the integrator which is the input to my plant, I can not run the Simulink due to the error
"Cannot pass the complex value to non-complex location"
I tried changing the data types of the integrator, then the same thing happens to other blocks in the Simulink. I also tried using absolute values, which of course gives real numbers, but turns out to be a very large number and generates high magnitude. I really need help in solving this issue. Can anyone help me in this/
Thanks in advance.
