I have created PR #7322 (https://github.com/numpy/numpy/pull/7322) to add a scale parameter to `sinc`. What this allows is to compute `sinc` as `sin(x)/x` or really `sin(n*x)/(n*x)` for arbitrary `n` instead of just `sin(pi*x)/(pi*x)` as is being done now. The parameter accepts two string arguments in addition to the actual scale value: 'normalized' and 'unnormalized'. 'normalized' is the default since that is the existing functionality. 'unnormalized' is equivalent to a `scale` of 1.0. The parameter also supports broadcasting against the input array. Regards, -Joe P.S. I would like to turn `sinc` into a `ufunc` at some point if the community approves. It would make the computation much cleaner (e.g., in-place `where`) and faster. It would also complement the existing trig functions nicely. The only question I have is whether or not it is possible to pass in optional parameters to ufuncs beyond the ones listed in http://docs.scipy.org/doc/numpy-1.10.0/reference/ufuncs.html#optional-keywor...
