How to freeze 'get method' while debugging program

For example，Add a program breakpoint on the 21th line“notify(obj,'UpdateGraph');” 24th line “[x,y] = MFunEval.grid(obj.Lm);”

The program steps to the 21th line ，you check “obj.hFun” .

At this point, the program will start to execute the “get method” in 24th line, but this is not what I want, and it will cause many accidents. matlab will open many build in function files. (start to execute the “get method” ------This makes sense, but I don't want the ‘get method’ to be triggered repeatedly when the debug view variable)

I want the program to execute sequentially.

How to not trigger the get method when viewing the variable without changing the program code. Are there any debugging tips here?

        function fofxy = set.hFun(obj,func)
            obj.hFun = func;
            notify(obj,'UpdateGraph');       %广播事件
        end
        function data = get.Data(obj)        %获取网格化数据
            [x,y] = MFunEval.grid(obj.Lm);
            matrix = obj.hFun(x,y);
            data.X = x;
            data.Y = y;
            data.Matrix = matrix;
        end
    end
    methods (Static)
        function [x,y] = grid(lim)       %网格化
            inc = (lim(2)-lim(1))/20;
            [x,y] = meshgrid(lim(1):inc:lim(2));
        end
    end
