how can i get 65=.0003?

if [.003 .006 .009 .012] is an array, how can i get [65 67 68 69] ,that means .003=65;.006=67 so on.how can i get this?

[the cyclist]

x = [0.003 0.006 0.009 0.012];

You want y = [65 67 68 69]? You can get this with the command

y = [65 67 68 69];

Oh, that's not what you meant? It's not really possible to tell what you actually wanted from your question, so maybe you should spend some more time explaining what you want, so that we understand.

Other than the obvious syntax provided by the cyclist isn't this just a maths problem rather than a Matlab problem? Or do you have the magic formula to go from one array to the other, but aren't sharing it?!

[Brendan Hamm]

It seems the equation you are looking for is:

y = x*1000/3 + 64;

but I have a feeling there is a bit more than this ...

[the cyclist]

@Brendan .... Note that the second array is not sequential

[James Tursa]

The obvious formula is:

>> x = [.003 .006 .009 .012]
x =
    0.0030    0.0060    0.0090    0.0120
>> y = 65 + floor(sqrt(x-x(1))*50)
y =
    65    67    68    69

[the cyclist]

Urgh. I thought the formula was

y = x./x + round(sort(roots([1 -265 26330 -1162520 19244544])))'

[James Tursa]

(at least my formula depends on the value of x ...)

[the cyclist]

Oh, fine:

y = round(sort(roots([1 (x/0.003)+[-270 27129 -1215982 20433656]])))'

Or... back on topic is the person looking for how to perform a table lookup?
