The response y in "stepwiseglm" has to be one column vector?
I found that the response y in "glmfit" can be two column matrix with the first column indicating the number of successes for each observation and the second column indicating the number of trials for each observation.
My response y is in format [successes; num of trials] and I want to use "stepwiseglm". How can I do that? Thank you so much!

You can specify the response variable y as a two-column vector, just as you did in glmfit. You must also then specify a binomial distribution, by adding the name-value pair like this ...
stepwiseglm(...,'Distribution','Binomial')

I don't know. You might want to post this as a new question, to get more visibility.
