help me.. how to fix this error. and run this prog. i need to put 2 variables in equations and get answers. so i took a range and a random number generater. is there any other way?

clc

clear all

n=[1:.001:7];

d=rand(1000,1);

%display(n)

    [a]=d*n;

 %   display([a])

[p]= (2*pi*[a]*cos(45))/300;

%display([p])

[A]=cos(p);

%display([A])

[B]=(1i.*sin(p)/n);

%display([B])

[C]=1i.*n.*sin(p);

%display([C])

[D]=cos(p);

%display([D])

%Reflection coefficient

[r]=real((n(1).*[A]+n(1).*n(3).*[B]+[C]-n(3).*[D])./(n(1).*[A]+n(1).*n(3).*[B]+[C]+n(3).*[D]));

%display ([r])

%[t]=(2.*n(1))./(n(1).*[A]+n(1).*n(3).*[B]+[C]+n(3).*[D]);

%display([t])

f=([r].^2)*100;

display(f)

In the line:

[C]=1i.*n.*sin(p);

n is 1-by-6001 and sin(p) is 1000-by-6001. To use .* the arrays must be the same size. I didn't delve into the code so I don't know what your intent here is. Maybe you want * instead of .* to do a matrix multiplication???

i want to take range of n as 1 to 7 and d as 1 to 100 for atleast 1000 values and gets answers some how. can u help me? main part is the range n and d needs to work and get values for the [a], which will get answers for rest equations. i am new to matlab. so if there is any other way to write program, please say so.
