If i had

DN= [[0.125 0.25 0.375 0.5 0.75 1 1.25 1.5 2 2.5];
OD=[0.405 0.540 0.675 0.84 1.05 1.315 1.66 1.9 2.375 2.875];
t=[0.068 0.088 0.091 0.109 0.113 0.133 0.14 0.145 0.154	0.203];

the above 3 matrix have the same no. of variables. and V varies from 1.5 to 3

ID = sqrt(4.*Q.* 0.000011574074./(pi.*V));
OD = ID + 2.*t;

and i need the OD function choose a the next large number from matrix above. Then align ID , t , DN with it.

@Mahmoud Sami: I do not have any idea of what "ASME standard" is. I do not understand the meaning of the other sentences of your comment also. Again: What is the wanted output for the given example input?

if i have F=[OD ID' t' DN'] as above comment I need 4 variables in that matrix with condition for V (1.5 :3 )

"and i need the OD function choose a the next large number from matrix above. "
interp1() with the 'next' option.

adjusted_OD = OD(bin);
adjusted_DN = DN(bin);
adjusted_t = t(bin);
