I'm getting invalid use of operator warnings when defining variables
clc
clear all
rho = 1025 %kg/m^3 - Seawater Density
c_d = 0.7 % Drag Coefficient (gentils, wang et al, 2017)
c_m = 2.0 % Inetia Coefficient
% Note: current is neligible
% Calulate wave length (Lamda)
g = 9.81; % gravity
T = 12 % secs - 8.3.1 corewind 1.2 Isle of Barra
H = 8 % m - 8.3.1 corewind 1.2 Isle of Barra
d = 120 % m - depth of column Table 3-1 OC3 Floating Paltform
lambda = ((g*T^2/2pi)tan*(H))(2pi*d/lambda)

Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct
matrices, use brackets instead of parentheses.

There is no implied multiplication. Also, the syntax for using tan is incorrect.
lambda = ((g*T^2/(2*pi))*tan(H))*(2*pi*d/lambda)
% ^^^^^^ ^ x ^ ^

The new error is because you cannot use a variable that has not yet been defined.

That is a warning letting you know those lines will print to the screen. To get rid of the yellow highlight, add a semicolon at the end of the line.
x=2
% vs
y=3;
