Need help on "maybe" simple MatLab problem

[Vauxdvihl]

Hello,
i try to use in MatLab the following equation:


AD_Volt_m_max=(Rmax_Kenn./(Rmax_Kenn+(Vorwider_Rmax*Tol_Vorwider_min))*(VCC_Versorg*Tol_VCC_max-VCE_Min)-(Poly_Rmin*(VCC_Versorg*Tol_VCC_max))/(Vorwider_Rmax*Tol_Vorwider_min+Poly_Rmin+Rmax_Kenn))

Rmax_Kenn is:

Rmax_Kenn = 10
20
30
40
50


If receive in Matlab the following Error meassge which i do not understand:

??? Error using ==> minus
Matrix dimensions must agree.

Error in ==> Kennlinie at 74
AD_Volt_m_max=(Rmax_Kenn./(Rmax_Kenn+(Vorwider_Rmax*Tol_Vorwider_min))*(VCC_Versorg*Tol_VCC_max-VCE_Min)-(Poly_Rmin*(VCC_Versorg*Tol_VCC_max))/(Vorwider_Rmax*Tol_Vorwider_min+Poly_Rmin+Rmax_Kenn))


Can please somebody help?
Thanks

upload all your *.m files so we can have a look at them

If you can't post your variables, then at least post the output of

size(Rmax_kenn)
size(Vorwider_Rmax)
etc...

??? Error using ==> minus
Matrix dimensions must agree.

The error means that the dimensions of your variables are not the same. Your row and column dimensions need to be the same for the operation you are attempting.

Post your .m file and we can help find the problem, otherwise just check the dimensions (and resulting dimensions of other operations) for all your variables in the particular problem equation.

Thanks a lot
I have fixed it
