I am trying to detect emotion using linear binary pattern. I got a histogram from the lbp image. My question is can I use the histogram as input in SVM classifier . If yes, how can I do it?

I've never heard of linear binary patterns. Perhaps you mean local binary patterns. You forgot to attach an image. I do not understand why LBP might be used to detect emotion, presumably the emotion of a person in a picture of their face. Can you explain the rationale for that? What is the size of the window you are using to obtain the LBP pixel value? The LBP image will depend on many things that have nothing to do with emotion such as angle of lighting, overall exposure level, etc. so I just don't see why the histogram will be of any help at all in determining emotion.

To convert any array into a vector, use (:):
vector = yourAray(:);
To find algorithms for virtually any image processing algorithm, see this: http://www.visionbib.com/bibliography/contentspeople.html#Face%20Recognition,%20Detection,%20Tracking,%20Gesture%20Recognition,%20Fingerprints,%20Biometrics
