double regression interpretation with vectors

Hello when we enter the following vectoric line shown bellow, we get result B=[b1,b2]

so how do i interpret the approximated value?

m10(nX1)=b1*v1(nX2)+b2*v2(nX2)
m2(nX1)=b1*v1(nX2)+b2*v2(nX2)

or

m10=b1*v1
m2=b2*v2

?

Thanks

[B,BINT,R] = regress([m10;m5],[v1;v2]);

Dunno. Depends upon what you mean by "interpret". There are additional optional return variables from regress that include a table of model statistics as well.
