matlab NaN

在MATLAB中，NaN表示“不是一个数字”，是一种特殊的值。NaN在数学运算中起到一个标记的作用，用来表示无效或未定义的结果。NaN可以用来占位、保持矩阵的规则性，或者表示计算过程中出现的非数字字符。在MATLAB中，NaN的比较结果有一些特殊的规则。例如，使用NaN进行逻辑运算时，NaN的结果通常都是false。此外，不同的NaN之间是不相等的。例如，a==NaN的结果将全部为false，而a~=NaN的结果将全部为true。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
