How can I take an integer like n=1:1:50 and get the output for each value?

I want to plot my output for each input and the input is from 1 to 50, but I am not sure why my code is not working.

n=1:50;   %my range, I want to check for each n values
f=n*175*10^6; % want to get frequency for each n
c=(sin(n*pi*d))/(n*pi*d) %d,tr,T these are my fixed values
d1=(sin((n*pi*tr)/T))/((n*pi*tr)/T);
In=2*d*Ipp*c*d1;
E=(In*f*L)/(0.8*r);   %I am not getting E for each n values

d = rand()  %since it was not defined

d = 0.0687

T = rand()  %since it was not defined

T = 0.3380

tr = rand()  %since it was not defined

tr = 0.7222

L = rand()  %since it was not defined

L = 0.8296

r = rand() %since it was not defined

r = 0.7237

Ipp = randi(255);  %since it was not defined

n=1:50;   %my range, I want to check for each n values
f=n*175*10^6; % want to get frequency for each n
c=(sin(n*pi*d))./(n*pi*d) %d,tr,T these are my fixed values

c = 1×50

0.9923 0.9692 0.9316 0.8803 0.8169 0.7431 0.6608 0.5722 0.4797 0.3857 0.2925 0.2024 0.1175 0.0397 -0.0295 -0.0887 -0.1371 -0.1742 -0.1996 -0.2137 -0.2171 -0.2105 -0.1951 -0.1724 -0.1438 -0.1110 -0.0756 -0.0394 -0.0039 0.0293

d1=(sin((n*pi*tr)/T))./((n*pi*tr)/T);
In=2*d*Ipp*c.*d1;
E=(In.*f*L)/(0.8*r); 

plot(n, E)

Without knowing the size of your variables and just presuming some variables to be scalar and others to be a vector, here is the corrected code that is based on the color operator (:) :

n=1:50;   %my range, I want to check for each n values
f=n*175*10^6; % want to get frequency for each n
c=(sin(n(:).*pi*d))./(n(:).*pi*d) %d,tr,T these are my fixed values
d1=(sin((n(:).*pi*tr)./T))./((n(:)*pi*tr)./T);
In=2*d(:).*Ipp*c*d1;
E=(In*f(:).*L)./(0.8*r);   %I am not getting E for each n values

Presumably, you have here d and L or r to be a vector with a certain length.
