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))));

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.

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
