Matrix dimensions must agree error when using element operators

I am confused on why I keep getting the error "Matrix dimensions must agree.". I am using element operators for the variable s_g=1.21.*WS./(g*rho.*TW).

C_Lmax=1.7;

g=32.2; % ft/s^2 %

rho=0.002377; % slugs/ft^3 %

% vectors %

TW=0.25:0.01:0.60;

WS=40:1:120;

% Matrices %

TWmat=meshgrid(0.25:0.01:0.60);

WSmat=meshgrid(40:1:120);

SGmat=meshgrid(TWMat,WSMat);

s_g=1.21.*WS./(g*rho.*TW);

Your variables

TW=0.25:0.01:0.60;
WS=40:1:120;

have a different number of elements. The element-wise operators require that all the vectors have equal length.
