A= [exp(sqrt(-w1/w2)*t) , exp(-sqrt(-w1/w2)*t) ]
I have this matrix with w1,w2 as contant and t is the time update every instance in simulink.
When I run the simulink, I am getting the error "Domain error: To compute complex results from real x, use 'sqrt(complex(x))". I tried looking for thr help, did not get the answer correctly. I understand from one of the answers that it is because the range limit is exceeded than expected. However I coulnot find the solution to solve my issue. Can anyone help me in this.

Hi,
Passing a negative value to the 'sqrt' function might be the reason for this error.
Refer to the last paragraph of the answer posted at the following link.
Your issue is not related to Matlab coder, But the reason might be the same.
