INF表示“无穷大”,是infinite的缩写。
NAN表示“无效数字”,是Not a number的缩写。

data11=isinf(data1);
[inf_r inf_c]=find(data11==1);
data1(inf_r,:)=[];

注意:第一句isinf输出的data11为logical 0,1.
第二句找到全为1即全为inf的标签。
第三句将inf全赋予空值。

你可以使用以下方法去除 MATLAB 中的 "inf" 值: 1. 使用 isinf() 函数来检测矩阵或向量中的 "inf" 值。例如,如果你有一个名为 A 的矩阵,你可以使用以下代码来找到 "inf" 值的索引: ```matlab idx = isinf(A); 2. 使用索引操作符将 "inf" 值替换为 NaN(非数字)。例如,你可以使用以下代码将 "inf" 值替换为 NaN: ```matlab A(idx) = NaN; 3. 如果你想删除包含 "inf" 值的行或列,可以使用以下代码: ```matlab A(any(isinf(A), 2), :) = []; 这会删除包含任何 "inf" 值的行。如果你想删除包含 "inf" 值的列,只需将第二个参数改为 `1` 即可。 希望这些方法能帮助到你!如有任何问题,请随时提问。
