use of greater than and less than

Hi,

I am very confused with the matlab format of a range. for example:

for L=10

if 0<L<5,
    rad=L+10
else
    rad=L+2
end
end

thats my code for saying that if L is less than 5, i want rad to be equal to L+2. however, the display is giving me 20! which is incorrect. What is the convention for defining a range in matlab?

[per isakson]

The MATLAB syntax is

    if 0<L && L<5,
        rad=L+10
    else
        rad=L+2
    end

or

    0<L & L<5

if L is a vector and

    for L = 1:10

Yes, the evaluation of 0<L<5 is confusing. My quick search in the documentation failed. Anyhow, from left to right

0<L evaluates to true and true<5 evaluates to true because true is converted to 1, which is less than 5. I guess this is a legacy from the eigthies.
