Can I fill empty pixels in a vector?

Hello

I try to explain my question better. I have an image in size of 466*700 and I have a vector on this image in size of 233*1, then some pixels of image hadn't been cover by vector, as you can see in figure1. Could you help me How can I fill these empty pixels on my vector and connect my vector?

Right know my vector is in size of 233*1 and by filling empty pixels I want to have a vector in size of 466*1.

I'll appreciate your help.

I'd use interp1(). By the way, your figure is not showing up.

Could you explain more?

How can I use interp1()? what about parameters of interp1()? Could I mail image to you please?

Try pasting your image into snag.gy and then using the image icon to insert it into your comment.

interp1() will let you get "in between" values for your 233 vector so that you will then have 466 values. See the help. Or search - I just uploaded code with it in the past few days.
