NaN+NaNi is a mathematical notation that represents the result of an undefined operation or calculation involving both real and imaginary numbers. NaN stands for "Not a Number," while NaNi represents "Not a Number" for imaginary numbers. This result typically occurs when performing calculations that result in an infinite or undefined value, such as dividing zero by zero. learn more over building educational app development.

Hey Antony Aravind,

MATLAB represents values that are not real or complex numbers with a special value called NaN which means 'Not a Number'. This means you are probably evaluating expressions like 0/0 or inf/inf or so on.

Similarly, when you have a complex number, the displayed values are real numbers + the complex part + 'i'. There must be some invalid expressions usage in the complex part of your program too.

Hope this helps!
