this is a part of my test and i cant find the mistake in this .

x = 1;
while  (x < 10)
x = x - 1;
disp( x )
end

Answer 1

[Star Strider]

The obvious observation is that ‘x’ is going to be less than 10 from the initial iteration through how many iterations it takes to be essentially equivalent to -Infinity.

[James Tursa]

Which is forever. At some point x will become large enough in magnitude that subtracting 1 will have no effect, and the loop will essentially become a "forever" loop.

[mohamad abou khalil]

so what is the suggested answer to avoid this loop (x=1:1:10) ?

[James Tursa]

Add 1 instead of subtract 1.

Answer 2

[mohamad abou khalil]

oh ok thank you very much

[Star Strider]

As always, my pleasure!

Answer 3

[mohamad abou khalil]

you guys have by anychance knowledge about binary systems (2 complement and negative numbers ?)

[James Tursa]

Yes. Open up a new question and we can help.

[Star Strider]

For my part, to an extent, although I’ve not done anything with them since graduate school (when we rode sauropods). However -Inf is still -Inf reagrdless of the base it is calcualted in. It just takes a different form.

Answer 4

[mohamad abou khalil]

ok so for example the question is that in 6 bit system which calculates negative numbers , they give us the binary form for example 100000 and we should write what number it represents

[John D'Errico]

Again, stop posting new answers just to make a comment or ask a new question. Ask a new question.

[mohamad abou khalil]

my question has nothing to do with matlab so im just asking these two guys , whats your problem man
