How to iterate vectors in matlab?

[Belathor]

Hi,

Is it possible to iterate through a list of vectors in matlab or octave? For example, I want to be able to prompt the user for a set of coordinates on a grid and have them stored in a way so that I can iterate over them one by one. I feel I need to do this because I want to make a dot representing a robot traverse the grid through those user specified points in order. I am really inexperienced with the language and I don't have any idea how I would do it.

Thanks for any help you could give!

A for loop can do this. If A is a matrix, and you use a for loop of the form for v = A, ..., v will iterate through the columns of A. Type help for or doc for in Matlab for more details.

For example,


>> A = [1 4.3; 2 91.1; 3 17]' % Note the transpose character at the end
A =
1.0000 2.0000 3.0000
4.3000 91.1000 17.0000
>> for p = A, str = sprintf('x=%f y=%f',p(1),p(2)); disp(str), end
x=1.000000 y=4.300000
x=2.000000 y=91.100000
x=3.000000 y=17.000000
>>

Thanks so much, WW! That worked perfectly.
