MATLAB: Hey, i have this program and i need to draw distribution of power Pr_dbm !

power distribution

c=3e8; Pt=9; Gt=1; Gr=1; f=60e9; d=1:0.05:50;

 for i=1:1:length(d)
Pr(i) = Pt*Gr*Gt*((c/(4*pi*d(i)*f))^2)
Pr_dbm(i)=10*log10(Pr(i));               % Pr sans path loss 
 end

like in the pictures but juste one pick

MATLAB: The below program is the Ids Vds characteristics of a DG MOSFET. and I am getting the error as Matrix dimensions must agree.. Please help me by fixing it

See the attached file and modified code..

clear all;
hfin=1;
tsi=20
W=2*hfin*tsi;
Vth=1;
Leff=180;
DIBL=1.127*(W\Leff);
vth=Vth-DIBL;
lambda=25*10^-5;
u=1360;
ld=0.1;
Ec=1.5*106;
Cox=60;
Vds=0:0.5:10;
vgs=input('ENTER THE Vgs in volts');
m=length(Vds);
for i=1:m
if vgs < Vth
current(1,i)=0;
current1(1,i)=0;
elseif Vds(i) >= (vgs - Vth)
current(1,i)=0.5* DIBL * ((vgs - Vth)^2)*(1+lambda*Vds(i));%Added DIBL
elseif Vds(i) < (vgs - Vth)
current(1,i)= DIBL*((vgs-Vth)*Vds(i) - 0.5*(Vds(i)^2))*(1+lambda*Vds(i)); %Simplified equation by approximation
end
end
plot(Vds,current(1,:),'b')
xlabel('Vds, V')
ylabel('Drain Current,A')

MATLAB: I need to convert this code(excell) to matlab language help

Function, For, If, Abs, and Exp go to function, if, for, abs, and exp (all lower case). Next i goes to end.

Put a % symbol in front of the "Newton-Raphson ...." line.

The function line should look like

Function output = ZFactor(Tr, Pr)

and the last line should be

output = 0.27 * Pr / rho / Tr

"To" in the for statement should be replaced with a colon :.

This

If test < 0.00001 Then Exit For

should be

if test < 0.00001 
    break;
end

Other than that I think it should be okay. You might want to add semicolons at the end of the lines to suppress echoing the result to the command window.
