a — Real component scalar | vector | matrix | multidimensional array

Real component, specified as a fi scalar, vector, matrix, or
multidimensional array.

The size of a must match the size of b, unless
one is a scalar. If either a or b is a scalar,
MATLAB^{®} expands the scalar to match the size of the other input.

Imaginary component, specified as a fi scalar, vector, matrix, or
multidimensional array.

The size of b must match the size of a, unless
one is a scalar. If either a or b is a scalar,
MATLAB expands the scalar to match the size of the other input.
