The Scilab's imag() Function

Navigating complex numbers in Scilab? The imag() function is your essential tool for identifying the imaginary part.

real(x)

In this context, x is our chosen complex number.

By deploying this function, you're granted immediate insight into the number's imaginary facet.

So, what exactly is this "imaginary part"? Envision a complex number structured as z=a+bi. Here, "a" represents the real part, while "b" is the imaginary counterpart. The "i" symbolizes the imaginary unit. The imag() function retrieves the coefficient "b" associated with the imaginary unit.

Let's delve into a tangible example.

Suppose you have a complex number, 3+4i

z = 3 + 4*%i;

To extract its imaginary aspect, simply input imag(z)

imag(z)

The result? A value of 4, which corresponds to the imaginary part of the complex number z=3+4i.

ans=
3.

Should you wish to discern the real part of the complex number, Scilab's real() function is at your disposal.
