Came across 'The expression to the left of the equals sign is not a valid target for an assignment' during compiling ode45 differential equation solver line 29, what would be the possible error.

if s==0
u=b*x(2)+c*x(1)-3*(1+abs(x(2)))*sign(s);
end
Best wishes

I believe line 29 is:
if s=0;
A single equal sign performs assignment. Two equal signs performs comparison.
x = 5; % Assign the value 5 to x
x == 5 % Returns true if x is equal to 5 and false if it is not.
The if keyword wants a comparison, not an assignment, as its condition.
