suppose img is image variable and if you have three dimensional image: bbBOx format is [ X Y Len Wid ]
img( X:X+Len-1, Y:Y+Wid-1, : ) = 0;

Thank you very much,i guess =1 not =0 , and i found other solution. for this case:
roi=[2.262763419483102e+02 2.55 11.593499005964213e+01 8.558429423459245e+01];
imgg = zeros(800,800,3);
imgg( roi(1):roi(1)+roi(3)-1, roi(2):roi(2)+roi(4)-1, : ) = 1;
imshow(imgg);
The other solution:
imgg = zeros(500,500,3);
img2=insertShape(imgg, 'FilledRectangle', [2.262763419483102e+02 2.55 11.593499005964213e+01 8.558429423459245e+01],'Color', {'white'}, 'Opacity', 1);
imshow(img2);
