matlab 图像上生成指定中心,指定大小的矩形窗

function PlaneWin = PlaneWindow(CentreCoorX,CentreCoorY,RadiusX,RadiusY,SizeImRow,SizeImColumn)
% 在图像上生成指定中心,指定大小的矩形窗(奇数*奇数)

% Input:
%           CentreCoorX(1*1)
%           CentreCoorY(1*1)

%           RadiusY(1*1)
%           SizeImRow(1*1)
%           SizeImColumn(1*1)
% Output:
