A part of my work need me to peak the peak from a graph of cyclic nature with time vs velocity. I tried to use treshold and and others options. to locate the maximum peak but could also include the local maximums . Is there anyway of picking the maximum value? such as sliding window ?

For local peaks I'd use findpeaks() in the Signal Processing Toolbox, or imregionalmax() in the Image Processing Toolbox. For a global peak, simply use the max function
[maxValue, indexOfMax] = max(yourSignal);

even i am also working on to find the peak of the signal i have tried inbuilt function [peak_value, peak_location] = findpeaks(Tx1Rx_1100mm_3plates);

After reading this: http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer, post your own question, along with screenshot of your signal, and code (including data) that we can copy and paste to reproduce your situation.

If you simply want to obtain the maximum(Peak) value of signal by excluding the local maximas, you can use the max function.
max_val=max(signal);
