re
result = re(x)
Input: x · Output: result
What it is
Real component of a Complex/CVec/CMat (identity — x passed through unchanged — when x is already real). x is a scalar, Vec, or Mat (real or complex).
Overloads
x can be scalar, Vec, Mat, or Complex.
2 forms. Each carries its own inputs, outputs and worked example — pick the tab for the one you are calling.
