下面是我的源程序
function dist = dtw(t,r)
n = size(t,1);
m = size(r,1);
% 帧匹配距离矩阵
d = zeros(n,m);
for i = 1:n
for j = 1:m
d(i,j) = sum((t(i,:)-r(j,:)).^2);
end
end
% 累积距离矩阵
D = ones(n,m) * realmax;
D(1,1) = d(1,1);
% 动态规划
for i = 2:n
for j = 1:m
D1 = D(i-1,j);
if j>1
D2 = D(i-1,j-1);
else
D2 = realmax;
end
if j>2
D3 = D(i-1,j-2);
else
D3 = realmax;
end
D(i,j) = d(i,j) + min([D1,D2,D3]);
end
end
dist = D(n,m);

你运行函数的时候加参数了么.
