Abstract function working in command line, not working in class as constant property

Question

Following function works at the command line, however not in the class as a constant property. I tried a lot of different combination with integral other function etc. but I was unable to solve it. Function

         enthalpyChange =  @(constants, temperatureIn, temperatureOut)integral(@(temperature)...
       F.heatCapacityOfLiquid(constants,temperature), temperatureIn,temperatureOut);

In Class

classdef F
    %FORMULAS Summary of this class goes here
    %   Detailed explanation goes here
    
    properties (Constant)
       
        %F.heatCapacityOfLiquid
        t = @(z) z *2
    end
    
    properties (Constant)
         enthalpyChange =  @(constants, temperatureIn, temperatureOut)integral(@(temperature)...
           F.heatCapacityOfLiquid(constants,temperature), temperatureIn,temperatureOut);
  
         heatCapacityOfLiquid = @(constants, temperature) constants(1)...
            + temperature * constants(2)... 
            + temperature.^2 * constants(3)...
            + temperature.^3 * constants(4);
%             heatCapacityOfLiquid = @F.HeatCapacityOfLiquid
    end
    methods (Static)
        function val = HeatCapacityOfLiquid(constants,temperature)
            
            formula = @(constants, temperature) constants(1)...
            + temperature * constants(2)... 
            + temperature.^2 * constants(3)...
            + temperature.^3 * constants(4);
            
            val = formula(constants, temperature);
        end
        
        
    end
