MATLAB: What does x=6 means

mean

x=6 y=7 disp(x&&y)

why is the answer 1

Best Answer

You can run the code and find out the answer. This is all about logical operations.

logical(6)&&logical(7);% by using && it converts 6 and 7 into their logical equivalent and AND them together
logical(-1);%logical of anything other than zero is 1

MATLAB: 10>6>4

"Can anyone explain this?"

MATLAB has a binary operator gt, e.g. A>B, but it does not have a ternary operator A>B>C. So your example

10>6>4

is exactly equivalent to this:

(10>6)>4

The part in the parentheses will only ever return the values 0 (false) or 1 (true), so the second comparison will always return false (unless you reduce the value 4 to 0 or less).

MATLAB: What means this

iter,eps: iter is number of iterations. eps stand for a small value. So your code runs either for 10 iterations or till the error goes less than given eps.
x=-2:0.01:2: This will create a array x from -2 to +2 with a difference of 0.01
plot(x,y1,'-b'): This will plot the values of array x wrt to array y1.
err : This is error variable.
at last >fprintf('%2.0f&10.4f%10.4f%10.4%f10.4f/n', result): this is to print the respective values on the screen i.e on command window.

MATLAB is an easy language. You can check all those your self with out asking these simple questions.
