Confidence intervals for glmfit-output betas?

Subject: Confidence intervals for glmfit-output betas?

Hi All-

Functions like regress provide the user with confidence intervals for the possible values of the output betas:

[B,BINT] = REGRESS(Y,X) returns a matrix BINT of 95% confidence
    intervals for B.

Is there an equivalent of this for glmfit? This is particularly relevant for null results; i.e., if the beta is close to zero, and the confidence interval includes zero and is narrow, that provides greater support for not rejecting the null hypothesis.

Is there a way to get glmfit to output the (1-alpha)th confidence intervals for each beta value that is output? Or is there a way to transform its output into those intervals?

The third output from glmfit is a structure.

The structure contains a field named "se" which contained the standard error for the regression coefficients.
