Question

whenever I create this function in editor

function r = Ymaxfinal(p,q)
r = ((-1000*p*q)/(27*(30*10^6)*0.163*(p+q)))*(p+(2*q))*((3*p(p+(2*q)))^0.5);
end

but when I call it in command window like Ymaxfinal(9,8)

it gives the error of Index exceeds matrix dimensions. plz help me

You're missing a multiplication ("*").

r = ((-1000*p*q)/(27*(30*10^6)*0.163*(p+q)))*(p+(2*q))*((3* --->p<---(p+(2*q)))^0.5);

Use this: r = ((-1000*p*q)/(27*(30*10^6)*0.163*(p+q)))*(p+(2*q))*((3*p*(p+(2*q)))^0.5);

Change this line:

r = ((-1000*p*q)/(27*(30*10^6)*0.163*(p+q)))*(p+(2*q))*((3*p(p+(2*q)))^0.5);

to

r = ((-1000*p*q)/(27*(30*10^6)*0.163*(p+q)))*(p+(2*q))*((3*p*(p+(2*q)))^0.5);

thanks it works
