i have set that contain complex number, then i get the greatest value using max function and get the smallest value using min function. For example the max value is -0.0115230+0.0474206i and the minimum value is 0.0026796 + 0.0006868i But if i give this command -0.0115230+0.0474206i > 0.0026796 + 0.0006868i it get the result ans=0. So, how did it happen ? should the result is ans=1 ?? please help. i am very confused

It can be proven that complex numbers cannot be ordered (under the definition of an ordered field). That means that you cannot compare complex numbers.

If x1=1.1+2*i and x2=1+2.1*i What is the smallest number ? You can't compare two complex numbers, you can compare their modulus
abs(x1)>abs(x2)
I think max and min function, in your case, are finding the max and min of abs(your_array)

Max is calculating the absolute value, and then taking the maximum value, despite being negative.
Greater than is taking the value farthest from negative infinity.
