说明：  包含1593个手写数字0~9.由semeion.data经matlab处理得到semeion.mat，可直接使用。原semeion.names转化为readme.m. mat：1593*266 每行为一个样本，其中256是16*16的手写数字展开，后10列为数字识别标签，例如：若第一列为1，则数字为0，第二列为1，数字为1.。。以此类推。 另外附matlab小例子，可以画出每个数字，更好理解。图像要反转和旋转一下才符合写作习惯。
(Contains 1593 handwritten digit 0~9. from semeion.data by MATLAB semeion.mat, can be used directly. The original semeion.names into readme.m. Mat:1593*266 A sample of each behavior, of which 256 are handwritten numeral 16*16, after the 10 column for the digital identification tag, for example: if the first row is 1, then the number is 0, second is 1, number 1.. And so on. In addition of MATLAB small example, can draw each digital, a better understanding of. The image you want to flip and rotation is consistent with the habit of writing.)
