我写了以下代码。我希望函数返回矩阵D&但是目前它只是返回矩阵' ans'这等于S.任何建议将不胜感激。感谢。
function [D,S] = sdQRS(QRS_cell)
%scales & dilates QRS complexes
m = length(QRS_cell{1}(:,1));
n = length(QRS_cell);
d1 = linspace(0.5,1.0,10);
d2 = linspace(1.0,2.0,21);
d = vertcat(d1',(d2(2:21))');
s1 = linspace(0.6,1.0,13);
s2 = linspace(1.0,1.5,18);
s = vertcat(s1',(s2(2:18))');
DIL = cell(n,1);
SCAL = cell(n,1);
for i = 1:n
DIL{i} = zeros(m,length(d));
SCAL{i} = zeros(m,length(d));
for j = 1:length(d)
DIL{i}(:,j) = interp1(QRS_cell{i}(:,1),QRS_cell{i}(:,2),QRS_cell{i}(:,1)/d(j),'linear','extrap');
SCAL{i}(:,j) = s(j)*QRS_cell{i}(:,2);
end
end
D = zeros(n);
S = zeros(n);
for k = 1:n
for l = 1:n
e = [];
t = [];
for a = 1:length(d)
e(a) = euc_dilQ(QRS_cell{k},QRS_cell{l},d(a));
t(a) = euc_scalQ(QRS_cell{k},QRS_cell{l},s(a));
end
[M,E] = min(e);
[M,T] = min(t);
D(k,l) = d(E);
S(k,l) = s(T);
end
end
答案 0 :(得分:1)
您可以指定Matlab函数以返回任意数量的输出值。在您的情况下,函数签名看起来像
function [D,S] = sdQRS(QRS_cell) {
d1 = linspace(0.5,1.0,10);
...
}
现在您可以输入
来调用该功能[D,S] = sdQRS(QRS_cell);
