Can someone explain this error to me?

Error using vertcat Dimensions of matrices being concatenated are not consistent.

Error in ProjectCE380>start_Callback (line 3796) A = [a1, a2, 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0;...

Error in gui_mainfcn (line 95) feval(varargin{:});

Error in ProjectCE380 (line 43) gui_mainfcn(gui_State, varargin{:});

What are the dimensions of a1 and a2, and any other variable you have in that line? If the first dimensions are not 1, they will not be consistent with the rest of the line.

for col = 1:mymass
      for row = 1:mymass
        A1(row,col)=A(row,col);

end

A2=A1;

for col = 1:mymass

        A1(row,col)=C(row);
    end
    B(col) = det(A1)/det(A2);
    A1=A2
end

this is what i have in my GUI and when i run the script it gives me that error.
