Real part of complex number
X = real(Z)
example
X = real(Z) returns the real part of each element in array Z.

Find the real part of the complex number Z.
Z = 2+3i; X = real(Z)
X = 2
Find the real part of each element in vector Z. The real function acts on Z element-wise.
real
Z = [0.5i 1+3i -2.2]; X = real(Z)
X = 1×3 0 1.0000 -2.2000
Input array, specified as a scalar, vector, matrix, or multidimensional array. real operates element-wise when Z is nonscalar.
