engineering formula solve - "index exceeds array bounds"

Hello,

this is a rework of a question i'd asked previously; my old cold ended up working fine with help, but my initial algebra was incorrect (multiple terms in denominator). I've re-worked the algebra, but get different error when plotting the equation - here's the code;

clear

clc

%initial parameters

%axial case

r = 1e-3;

d = 0.5e-3;

l = 2e-3;

mu = 0.6;

%equations

P = 200000:100000:2700000;

s = P*r/(2*(r-d));

g = s/2;

Y = ((3*(r^2)*s) - 3*(d^2)*((P)-s))/(2*l*mu(d*g-g*r+3*(P)*r));

plot(Y,P)

Index exceeds array bounds.

Error in iepattempt2 (line 20)

Y = ((3*(r^2)*s) - 3*(d^2)*((P)-s))/(2*l*mu(d*g-g*r+3*(P)*r));

Any assistance is appreciated once more,

Rich

Y = ((3*(r^2)*s) - 3*(d^2)*((P)-s))./(2*l*mu*(d*g-g*r+3*(P)*r));
