c = convn(a,b) : computes the convolution of an iData object with a response function @iData/convn function to compute the convolution of data sets with automatic centering and normalization of the filter. This is a shortcut for conv(a,b, 'same pad background center normalize') When used with a single scalar value, it is used as a width to build a gaussian function, with same width along all dimensions When used with a vector of same length as the object dimension, a nD gaussian function with width as vector elements along each diemsions input: a: object or array, signal (iData or numeric) b: object or array, filter (iData or numeric) output: c: object or array (iData) ex: c=convn(a,b); Version: Aug. 22, 2017 See also iData, iData/times, iData/conv, iData/fft, iData/xcorr, fconv, fconvn, fxcorr

- double d = double(s) : convert iData into doubles
- end b = end(s,index,n) : end value for iData objects
- getaxis [val, lab] = getaxis(s, AxisIndex) : get iData axis value and label
- isscalar b = isscalar(s) : True for scalar iData objects
- mean b = mean(s, dim) : mean value of iData object
- ndims d = ndims(s) : get the dimensionality of iData object

- smooth Z = smooth(Y) : smooth iData objects
