How to correct this error?"Subscripted assignment dimension mismatch."
显示 更早的评论
Hi, I would like to create a column vector which is called ub with for loop but I got this error: Subscripted assignment dimension mismatch.
Error in Test_WSVM (line 74) ub(i,1)= C*(7/15)*ones(n,1); » Here is my code
if true
clc;clear;close all;
%Load Data
load Unblanced_Data.mat
x = unblanced_data;
%%Data Normalaization
m=size(x,1);
xMean = repmat(mean(x),m,1);
xStd = repmat(std(x),m,1);
x_norm = (x - xMean)./(xStd);
%%Training SVM
x_1=[x_norm(1:6400,:); x_norm(8001:13600,:)];
y_1=[-ones(6400,1);ones(5600,1) ];
TrainInputs = (x_1)';
TrainTargets =(y_1)';
ClassFault = find(TrainTargets == 1);
ClassNormal = find(TrainTargets == -1);
n=numel(TrainTargets);
%% Design SVM
C=10;
sigma=1.5;
Kernel=@(xi,xj) exp(-1/(2*sigma^2)*norm(xi-xj)^2);
H=zeros(n,n);
for i=1:n
for j=i:n
H(i,j)=TrainTargets(i)*TrainTargets(j)*Kernel(TrainInputs(:,i),TrainInputs(:,j));
H(j,i)=H(i,j);
end
end
f=-ones(n,1);
Aeq=(y_1)';
beq=0;
lb=zeros(n,1);
ub = zeros(n,1);
for i=1:n
if (TrainTargets(1,i) == 1)
ub(i,1)= C*(8/15)*ones(n,1);
else
ub(i,1)= C*(7/15)*ones(n,1);
end
end
options = optimset('Algorithm', 'interior-point-convex','Display',...
'off','MaxIter',20);
alpha=quadprog(H,f,[],[],Aeq,beq,lb,ub,[],options)';
end
Any helps would be appreciated.

ub(i,1) is a scalar element, but ones(n,1) is a vector if n>1. You can't assign a vector to a scalar element.
