- SCALAR:
-
- In RLaB scalar numerics belong to the same class as matrix
- numerics. Other than size, there is little distinction between
- an array (matrix) of numbers, and a single number (scalar).
-
- > a = 1
- 1
- > b = 1+2*sqrt(2+a)

-
- Scalars can have real, or complex numeric values (a real part,
- and an imaginary part). A complex scalar is created by using a
- complex constant. A complex constant is entered with either an
- `i' or a `j' denoting the imaginary number...
-
- 12.5i
-
- 2j
-
- No spaces are allowed between the number and the `i' or `j'.
- So a complex variable can be created like:
-
- a = 1.5 - 3j
-
- You can also use the MATLAB approach...
-
- i = sqrt(-1);
- a = 1.5 - 3*i
-
- See `help COMPLEX' for more info on complex variables.
