- COMPLEX:
-
- RLaB supports COMPLEX data types. The "type" of a variable is
- revealed by typing:
-
- var.type
-
- or
-
- show(var)
-
- In the 1st instance the return value is a string, in the 2nd
- instance, the return value is a string matrix.
-
- Complex variables can be used via the MATLAB syntax:
-
- i = sqrt(-1)
-
- z = 1 + 2*i
-
- z = a + b*i
-
- or with RLaB's complex constant feature:
-
- z = 1 + 2i
-
- z = 1 + 2j // equivalent to the previous statement
-
- The complex constants `i' and `j' do not interfere with
- ordinary variables `i' and `j' since the complex constants
- must immediately follow a number to be interpreted as a
- complex constant.
-
- For example:
-
- 1i // valid complex constant
-
- 1 i // two separate statements
-
- Wherever it makes sense, built-in functions will accept real,
- and complex arguments. For example, inv(), det(), eig(), fft()
- will accept both real and complex inputs.
