谁帮忙给这段程序加个注释啊。。谢谢哦
这是计算图像投影的函数。。哪位高手帮忙给加个注释，小弟感激不尽啊。。function = radon(I,theta,n)；
iptchecknargin(1, 3, nargin, mfilename)
iptcheckinput(I,{'numeric','logical'},{'nonsparse'},mfilename,'I',1);
if (nargin < 2)
theta = 0:179;
else
ptcheckinput(theta,{'double'},{'nonsparse'},mfilename,'THETA',2);
end
= radonc(double(I),theta);
if (nargin == 3) && (size(P,1) ~= n)
% Grandfathered syntax
% Resize along the column direction using linear interpolation.
new_r = linspace(min(r), max(r), n)';
P = interp1(r(:), P, new_r(:), '*linear');
P = P * length(r) / length(new_r);% keeps scaling roughly the same
r = new_r;
end help iptchecknargin
help iptcheckinput
...
有些函数好像找不到!
