Resample uniform or nonuniform data to new fixed rate

interpolates the input signal to an intermediate uniform grid with a sample spacing
of (`y`

= resample(`x`

,`tx`

,`fs`

,`p`

,`q`

)`p`

/`q`

)/`fs`

. The
function then filters the result to upsample it by `p`

and
downsample it by `q`

, resulting in a final sample rate of
`fs`

. For best results, ensure that
`fs`

× `q`

/`p`

is at least twice as large as the highest frequency component of
`x`

.

`resample`

performs an FIR design using `firls`

, normalizes the result to account
for the processing gain of the window, and then implements a rate
change using `upfirdn`

.
