The sc value in the equation B should be function of x
sc(x) that depends on range x= 0:0.01:10

I want to write the varibale sc in Equation B as a function of x
B(x) = rhoref/ rhot * x^2/ xref^2 * exp ( -2 * atm * xref)^10^-er/10 / T * sc(x)
x is the range from 0 to 10

Then define
sc = @(x) ... % whatever the definition is.
But since you have set the values of x previously you could just set
sc = ... % directly in terms of x

  1. You need to define sc before using it in B.
  2. In B you have ...1000/dref*dref.... This just means the dref va;lues cancel each other out. Did you mean ...1000/(dref*dref)...?
PS Upload the actual code, niot an image. Use the > symbol above.

You need to define sc.
If you don't know what sc is, how is Matlab to know?
