Please describe what you want to do. What is your ‘gb’ variable?

The function scatterd is not a standard matlab function, do you mean scatter(d)? Is it a function you made? Is it in the correct folder?

Can you explain what you want to do? The scatter function is used for plotting data. You need to give the function at least to inputs, x & y coordinates of the points you are going to plot.

Actually, I searched about Karskual wallis feature selection code to select fingerprint features that I extract it earlier by using gabor filter and this what I get as a result.for now ,I do not know if they use it as built in function or It is function that they do .They did not include any comment for that except it is kraskual wallis step.

You have a space between the name and the argumment,
scatterd (p);
write
scatterd(p);

spaces between functions/matrices/anything and brackets are allowed and some people actually prefer it this way. This is certainly not the cause of the error.

MATLAB is case sensitive. So in this:
p = kruskalwallis(cA)
scatter(P);
P is a different variable than p. Put this in your code and tell me what it says:
whos P
whos p
If you still need help, attach myfinger.jpg, and the code for kruskalwallis if it's not part of your wavelets toolbox. I've never heard of that filter though I have heard of a Wallis filter, which is a local filter that tries to make every window have the same, specified mean and standard deviation. I can't try your code though because I don't have the wavelet toolbox.

No, scatterd() is neither a function in Statistics Toolbox nor Wavelet Toolbox, in R2014b.

I am working on Matlab R2013a but why it does not accept this function scatter(p)even if i did all your suggestions about the correction .any way I will delete it to solve this error.
