Can you clarify this sentence: How can I find numbers of column that this vector goes from them?

The image did not get attached.

I'd say your vector leaves from column #1. And goes to column #2. Am I missing something?

[Walter Roberson]

My guess is that the vectors are drawn in the image, and need to be located and their pixel length determined.

Hello I try to attach image again.

I have a vector on an image, I need to know the elements that this vector goes on them.

Neither Firefox nor Internet Explorer can display this image. Anyway, if you drew the vector on the image then how do you not know what rows and columns it started and stopped on????

I didn't draw this vector myself.

I have an image in size of 466*700. I down sample this image to 4 image in size of 233*350. I plot 4 vectors on this four images by a function, and I compose this 4 image together. right know I SEE those vector in my original image, but I want to know elements that vector goes on image. I use find function to determine these elements, But they aren't in right order.

Make it easy for us to help you. I'm not feeling too motivated right now. Read this: http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer. And try much harder to attach images or screenshots.
