Remove intercept with "regress"

Hello everyone!

I would like to run a multiple linear regression, but dont want any intercept in the output (i want to remove it, because i'm facing a multicolinearity issue). Can someone help me? Here is a piece of my code :

[b17, bint17,~,~,stats17] = regress(TrimROA, [ones(length(TrimROA),1) TrimOPEXP_LP TrimBPSM TrimWO TrimCPB TrimDEBT_EQU],0.1)

Thanks a lot!

I think that all you need to do is remove the first column from your second argument (i.e. the column of 1's).

[b17, bint17,~,~,stats17] = regress(TrimROA, [TrimOPEXP_LP TrimBPSM TrimWO TrimCPB TrimDEBT_EQU],0.1)

Thanks, but i still have an issue^^. I removed the column of ones :

ones(length(TrimROA),1)

But i got this error message now :

Warning: R-square and the F statistic are not well-defined unless X has a column of ones.
Type "help regress" for more information. 
> In regress at 163

This is a problem, because i need to have a reliable R-square for my work. Any idea?
