if strcmp(subInfo.gender, 'male')

% 显示男性图片

imshow(maleImage);

else

% 显示女性图片

imshow(femaleImage);

end

您好，我发现很多时候在设置Block Loop中，拉丁方会报错。比如：我在BlockLoop里面设置了四种timeline任务条件，我想实现被试间的四个任务顺序的平衡。但是如果我在divisor number这里填写4，就会出现如下报错，错误使用 vertcat，要串联的数组的维度不一致。如果我填24的话，又会出现语句没有匹配的 END的错误。如果是两个任务实现被试间ABBA也会出现类似的情况。
