error when running a function

guys please i need help.. am getting error when i run this.

function Y= microstrip(L,W)

fr= 6.2; h=2; er=2.25;

ee= ((er+1)/2)+((er-1)/(2*sqrt(1+10*(h/W))));

deltw= (0.412*h)*(((ee+0.3)*((W/h)+0.264))/((ee+0.258)*((W/h)+0.813)));

Y=300000000/(2*((L+deltw)*(sqrt(ee))));

end

Error

Not enough input arguments.

Error in microstrip (line 3)

ee= ((er+1)/2)+((er-1)/(2*sqrt(1+10*(h/W))));

What inputs are you using? Please copy & paste entire error message for us.

Thanx james for your fast response. :)

i got Not enough input arguments.

Error in microstrip (line 3)

ee= ((er+1)/2)+((er-1)/(2*sqrt(1+10*(h/W))));

I'll use this function on my optimization tool box.

Well, are you calling the function with two inputs? How are you calling it?

[mohamed ali]

actually i didnt reach to the part of calling, because when i try to run this script (function) it giving me error.

[James Tursa]

You did call it because the funciton is returning an error. Maybe you didn't think you did ... but you did. DId you just push the green triangle "go" button in the editor? Because that is equivalent to calling the function with no inputs.

[mohamed ali]

yes , i did :)

i shouldn't ?

Answer 1

Do not push the green triangle "go" button in the editor since that calls the function without any input arguments. Instead, call it from somewhere else with inputs. E.g., at the command line:

L = rand; % whatever
W = rand; % whatever
Y = microstrip(L,W); % called with inputs
