i have made these four .m files but when i try to run them this error is displayed 'Function definitions are not permitted at the prompt or in scripts'
i read this in a solution to form .m file for the functions separately but then again the same msg was displayed....

In a function file, you can start with any number of blank lines and comment lines, but after that the very first line has to be a "function" line. If you have anything else at all (other than blanks / comments) before the "function" line, then MATLAB will consider the file to be a "script".

If I'm reading your website correctly, you're saying that this is a script named fftAI.m:
[d, time] = getdata(ai, ai.SamplesPerTrigger);
[f, mag] = localDaqfft(d,Fs,blockSize);
data.getdata = [d time];
function [f, mag] = localDaqfft(data, Fs, blockSize)
xFFT = fft(data);
xfft = abs(xFFT);
index = find(xfft == 0);
xfft(index) = 1e-17;
mag = 20*log10(xfft);
mag = mag(1:blockSize/2);
f = (0:length(mag)-1)*Fx/blockSie;
f = f(:);
you can't have function call outs in scripts like that. localDaqfft will need to be it's own m file.

function bw=adaptivethreshold(IM,ws,C,tm) if (nargin<3) error('You must provide the image IM, the window size ws, and C.'); elseif (nargin==3) tm=0; elseif (tm~=0 && tm~=1) error('tm must be 0 or 1.'); end
IM=mat2gray(IM);
if tm==0 mIM=imfilter(IM,fspecial('average',ws),'replicate'); else mIM=medfilt2(IM,[ws ws]); end sIM=mIM-IM-C; bw=im2bw(sIM,0); bw=imcomplement(bw); I m getting the same error.what should I do?
