Good evening. I am doing k means clustering problem by taking iris data set. At the time of normalization i am eliminating the last column i.e my class level. After doing normalization can i add the 5th column value from the original data set again to the normalized data set.

Don't need to "eliminate" anything, just select the column(s) wanted as input arguments.
For an array X of 5 (say) columns of which only want to use first four,
idx=kmeans(X(:,1:4)); % cluster over first four columns
