[交流] 【求助】菜鸟求助 matlab 近红外光谱小波变换问题

function coefs = cwt_h(signal,scale)
% CWT with Haar wavelet basis %   
signal = signal(:)';  
len = length(signal);   
coefs = zeros(1,len);   
precis = 10;   
[psi,psi_x] = get_psi(precis);   
f = get_filt(psi,psi_x,scale);   
coefs = -sqrt(scale)*keepcent(diff(conv(signal,f)),len);
% % end of function %

你用什么近红外仪啊，主要是化学计量软件，机器上应该都配备的，我用的是brimrose的luminar4030自带的snap32.懂得也不多，希望多交流
