excuse my laziness for not looking this up, I googled it but could not find
a solution.
matlab has a
isreal(array)
where if the array is full of real numbers the value returned is 1.
I'm translating matlab code and ran across
if ~isreal(array)
array = abs(array)
Is there a way to check to see if a number is real or complex? and if so is
there a way to extract the(a + ib) because the absolute value of a complex
number is like the pythagorean therom on a and b?
thanks for your help,
Kenny
