Some results in MATLAB seem very strange,
I get a vector of numbers like this:
0.2104 + 0.0000i
0.8404 + 0.0000i
0.2564 + 0.0000i
...
How can I convert these to a normal set of numbers?
I am completing maximum likelihood estimation and recording the p-values
here is a longer list of numbers out of my 5000

It is only this one number 0.999999999954056 - 750325.850663069i in the entire 5000 that seems off. Can I just ignore the imaginary part there?
You are getting complex numbers. I assume you want real numbers. You can do that using the function real(). real() will capture the "real" part of the complex number, a number that is made up by real and imaginary parts, as real+imaginary, often the imaginary part labelled as i so you don't think it a sum.
However, note: If this is the output of some computation, its likely that the maths you are doing are resulting in imaginary/complex numbers (e.g. sqrt(-1) results in 1i or just i). By your lack of knowledge of what complex numbers are and surprise at finding them, I suspect that the maths that lead to those results are not supposed to return complex numbers, and there is a high likelihood that you have a bug in your code.
