matlab里lp2vec是什么函数

Answer 1

lp2vec是自定义函数，是自行编写有关将LP输出成矢量形式方面的函数。
function [c, s] = lp2vec(y)
% LP2VEC Convert the output of the LP into a vector form
% [c, s] = lp2vec(y)

% Input:

% y: an output of LPD
% Output:

% c: a column vector that contains all LP coefficients
% s: size vectors of each LP output layer, one per row
% See also: LPD, VEC2LP

n = length(y);

s = zeros(n, ndims(y{1}));
% Save the sizes of cells of y into s

for l = 1:n
s(l, :) = size(y{l});
end
% Flatten each layer of the LP into a vector and concatenate them

ind = 0;
c = zeros(sum(prod(s, 2)), 1);
for l = 1:n

nc = prod(size(y{l}));
c(ind+1:ind+nc) = y{l}(:);
ind = ind + nc;
end
