Multi-dimensional Gaussian filter.
Parameters : | input : array-like
sigma : scalar or sequence of scalars
order : {0, 1, 2, 3} or sequence from same set, optional
output : array, optional
mode : {‘reflect’,’constant’,’nearest’,’mirror’, ‘wrap’}, optional
cval : scalar, optional

Notes
The multi-dimensional filter is implemented as a sequence of one-dimensional convolution filters. The intermediate arrays are stored in the same data type as the output. Therefore, for output types with a limited precision, the results may be imprecise because intermediate results may be stored with insufficient precision.
