In my code some variables are getting negative values, I want to make minimum as zero, therefore when they get negative values I want them to assign them zero value.HOW to do it?

In my code some variables are getting negative values, I want to make minimum as zero, therefore when they get negative values I want them to assign them zero value.The variables are N and P. I want whenever N or P goes negative than if N or P <=0 than N or P = 0 and Gp = 0. I am unable to do so in my for loop. Need Assistance!

N = max(0, N);

Thanks Mr Walterson, Also there is Gp a variable which is checked for N/P ratio and when one of N and P gets zero it shows rank deficient error.

Also where should i place this

    N = max(0, N);

in for loop for i.

Also i am getting

Error using vertcat
Dimensions of matrices being concatenated are not consistent.

Error in code (line 203)
I7 = [A;N;P;S;Cseq;Mi;CO2_actual] ;

plaese help

You wrote,

"I want to make minimum as zero, therefore when they get negative values I want them to assign them zero value"

Add the line N = max(0,N) at the point at which you want to make the negative numbers into 0.

okay...thanks
