hello everybody .... hope you are well :)

maybe it's a silly question but really I could not fine the answer :S

I thought it divide two arrays, so i defined x = [1 2 3]; y = [4 5 6]; x/y

but the answer was different :S

anyone can give the idea plz :$

1:3/4:6 is the same as 1 : (3/4) : 6.

And I think you want x ./ y which is an element-by-element divide, instead of x/y which is a matrix inversion.

mmmm yeah it takes a step and find the series ...

but x./y also different my friend from it because their as we found its only find a series.

thank you ... :)

Well, what do you want as the output? x ./ y gives [0.25, 0.4, 0.5]. Evidently that "series" or array is not what you want but we don't know what you do want.

when i type this :

1:3/4:6

Read section "operator precedence" in the Matlab section on arithmetic operators. Followed on by

doc colon

The combination explains all...
