试试这个 -

%%// Start and stop row numbers
start_ind = [2 103 304 405 506 607 708 809 1000 :100: 1400];
stop_ind = [start_ind(1:8)+100  start_ind(9:end) + 99];

data = xlsread('CANCER.xls'); %%// Read data in one-go
C = zeros(2,numel(start_ind)); %%// Place holder for C values 
for k1 = 1:numel(start_ind)
    num = data(start_ind(k1):stop_ind(k1),3); %%// Data for the specified range 
    [IDX,C(:,k1)] = kmeans(num,2); %%// Do the calculations
end
kmns = reshape(C,[],1); %%// Final result
