Hello ,

I am working with the Pulse signals and I want to get a window of say length 'x' moving over the entire pulse signal(comprised of different pulses).

Each time when the window operates with a particular length on a part of pulse signal which is containing different pulses has to give output both the avg of Max values of the all the pulses and also the avg of Min values of all the pulses present in the particular window size.If not possible then only the avg of Max values of the all the pulses.

Thanks.

在 MATLAB Online 中打开

I know you have the Image Processing Toolbox, souse cat(2,...) to stick all your signals together in a 2D array, then call conv2() to get the means, call imdilate() to get the maxes, and imerode() to get the mins. It's only 5 lines of code total - give it a try.

out2d = cat(2,.....
minSignal = imerode(out2d,......
maxSignal = imdilate(out2d,......
meanMinSignal = conv2(minSignal ,.....  
meanMaxSignal = conv2(maxSignal ,.....

See if you can finish it.

I looked at your answer here

http://www.mathworks.com/matlabcentral/answers/88281-how-can-i-count-peaks-above-a-threshold

It is quiet good that is similar to what I m looking but I dont have Image Processing Toolbox as I'm permitted to use only the signal Processing toolbox.

I need similar method that can work with the signal processing toolbox.

Will there be any way to find out this?

You can use blockproc() to do the erosion and dilation. They're just the local min and max, respectively. See demos attached below.
