How to shift a filter into higher frequency band?

Hello,

Could you please explain how to shift a low pass filter into higher frequency in a Matlab code? For example; how can we make it for a low pass sinc filter?

Thanks...

Alternatively, in theory, a sinc filter is just the Fourier transform of a rectangular window.
