the input N change in formula input

hi can any one tell me i have a formula D = −(2πc/λ^2) N where the c and λ are constant.but i want to make a program using matlab in which i give the any value of N its show the output. can any one tell m what i do... thnx

Answer 1

[Azzi Abdelmalek]

Lamda=1;
c=2;
D = @(N)  -(2*pi*c/Lamda^2)*N
D(5)  % for N=5

[sonu]

D =

    @(N)-(2*pi*c/Lamda^2)*N

its show only this answer..how i put the value of n

[Walter Roberson]

D(input('ENTER THE VALUE OD N'))

[Azzi Abdelmalek]

You can use

N=input('enter N')
Lamda=1;
c=2;
D = -(2*pi*c/Lamda^2)*N;
display(D)
