Function stream_dct::dct_2d [−] [src]

pub fn dct_2d(packed_2d: &[f64], rowstride: usize) -> Vec<f64>

Perform a 2D DCT on a 1D-packed vector with a given rowstride.

E.g. a vector of length 9 with a rowstride of 3 will be processed as a 3x3 matrix.

Returns a vector of the same size packed in the same way.

Search Tricks

Prefix searches with a type followed by a colon (e.g. fn:) to restrict the search to a given type.

Accepted types are: fn, mod, struct, enum, trait, type, macro, and const.

Search functions by type signature (e.g. vec -> usize or * -> vec)
