我用excel link 将excel中的数据导入给<BR>matlab的一个变量的时候，因为数据是分数跟整数的混合。但是，导入的数据在内存中显示是<BR>char的形式 即变量的类型不是本来要的double<BR>而是excel的cell型了<BR>有办法可以解决么？<BR><BR>比如说本来是这样的数据<BR>3/5  19/30  1  0  0<BR>导入到里面却变成<BR>'3/5' ' 19/30'   [1] [ 0]  [0]

还有就是如果把前面的那些分数项 如3/5这样的去掉 或者改成1 0这样的数 也可以显示正常

'3/5' 这种格式没办法，可以对cell array进行操作
