deconvolution deconvolve.m Given a system impulse response h[n] and test response y[n], this algorithm deconvolves the test response with the impulse response to determine the input x[n] as X(jw) = Y(jw)/H(jw). Eliminate some noise, but is still very rough NOTE: Assumes all signals are the same length. Use sigcorrect.m to equalize their lengths if they are different. use: deconvolve(impresp,test,testresp) variables: impresp: impulse response of system test: test input to system testresp: test response of system

说明：  to detect branch and end points of bones
