matlab调用C++文件出错

% Results = DIAMOND_VANISH(InputImg, Normalization, SpaceSize, PatchSize)
%
% Input:
% InputImg input image
% Normalization float number;
% normalization of the image (1 means normalization form -1 to 1)
% SpaceSize int number;
% resolution of the accumulation space (final space has dims SpaceSize x SpaceSize)
% PatchSize int row vector;
% radius of a patch, from which edge pixels are extracted and use for ellipse fitting for detection of orientation of the edge point
%
% Output:
% Results structure with fields:
% Results.Space accumulated diamond space (further is used for orthogonalization)
% Results.PC_VanP positions of the maxima in R.Space
% Results.PC_VanP_Norm normalized position of the maxima (R.Space bounded from -1 to 1)
% Results.CC_VanP position of the vanishing point in the input image coordinates
%find edge points

%find lines
