Regstats for a regression on a linear term only

I want to regress Y on a linear term only (y = ax). I want the t-statistic of this regression, so I want to use regstat.

Does anyone know what I should do, to make a regression without the constant term?

"Alternatively, model can be a matrix of model terms accepted by the x2fx function. See x2fx for a description of this matrix and for a description of the order in which terms appear. You can use this matrix to specify other models including ones without a constant term."

I would use the new linear model class http://www.mathworks.com/help/stats/linearmodel.fit.html LinearModel.fit

'Y ~ X - 1' is a three-variable linear model without intercept.
