I am not certain what you want.
Try this:
ElectricityPrice = randi(250, 50, 1); % Create Data
Constant = 42; % Create Constant
b = 1; % Define ‘b’
c = 2; % Define ‘c’
Lv = ElectricityPrice > Constant; % Logical Vector
ElectricityPrice(Lv,2) = b; % Define Second Column
ElectricityPrice(~Lv,2) = c; % Define Second Column
That sets the second column (to create a different vector, if that is what you want, is easily done) to either ‘a’ or ‘b’.
