Question

Is there an equivalent MATLAB function for the range() function in Python?

I'd really like to be able to type something like range(-10, 11, 5) and get back [-10, -5, 0, 5, 10] instead of having to write out the entire range by hand.

Answer 1

There are two relevant functions. The colon : operator, you can use the linspace function. The best function to use depends on what you want to specify.

Examples:

x = -10:5:10;              % Count by 5's from -10 to 10.  (or "colon(-10, 5, 10)")
x = linspace(-10, 10, 5);  % 5 even increments between -10 and 10

The result of the colon operator will always include the first argument and the desired spacing, but generally will not include the last argument. (e.g. x = -10:5:11).

The linspace function will always include the desired first and last elements, but will the element spacing will vary. (e.g. linspace(-10, 11, 5)).

Answer 2

Yes, there is the : operator. The command -10:5:11 would produce the vector [-10, -5, 0, 5, 10];
