What functions does Matlab have about complex numbers?

There are several functions in MATLAB related to complex numbers.

1. imag(x): returns the imaginary part of the complex number x.
2. real(x): returns the real part of the complex number x.
3. conj(x)：returns the complex conjugate of the complex number x.
4. Return the magnitude of the complex number x.
5. angle(x): returns the phase angle (in radians) of the complex number x.
6. square root of x: returns the square root of x.
7. exp(x): returns the power of e raised to the xth power.
8. log(x) : returns the natural logarithm of x.
9. log base 10 of x: returns the logarithm of x with base 10.
10. sine of x: returns the sine value of x.
11. cos(x) returns the cosine value of x.
12. tan(x): returns the tangent value of x.
13. Sinh(x) returns the hyperbolic sine value of x.
14. cosh(x): returns the hyperbolic cosine value of x.
15. tanh(x): Returns the hyperbolic tangent value of x.

These functions can be used to perform various operations and mathematical calculations on complex numbers.
