MATLAB程序看不懂[dxdy]=meshgrid(-r:r);h=exp(-(dx.^2+dy.^2)/(2*sigma_s^2));xp=padarray(x,[rr],’symmetric’)

MATLAB程序看不懂[dx dy] = meshgrid(-r:r);h = exp(- (dx.^2 + dy.^2) / (2 * sigma_s^2));xp = padarray(x,[r r],’symmetric’);yp = padarray(y,[r r],’symmetric’);xt = zeros(size(x));parfor p = 1:numel(x),[i j] = ind2sub(size(x),p);求上面程
MATLAB程序看不懂

求上面程序每步的注解!
