Imaginary Part of Complex Number

Open Live Script

Find the imaginary part of the complex number Z.

Z = 2+3i;
Y = imag(Z)

Y = 3

Imaginary Part of Vector of Complex Values

Open Live Script

Find the imaginary part of each element in vector Z. The imag function acts on Z element-wise.

Z = [0.5i 1+3i -2.2];
Y = imag(Z)

Y = 1×3
