1.易混的命令

e^3–>exp(3)
ln(x)–>log(x)
log10(x)—>log10(x)
log2(x)—>log2(x)
根号4—>sqrt(4)或者4^05
2B=10—>错误：变量开头不能用数字

who查看当前有哪些变量；whos可以用于查看变量的具体数据类型。

matlab">>> who

您的变量为:

A    B    a    ans  

matlab">>> whos
  Name      Size            Bytes  Class     Attributes

  A         1x1                 8  double              
  B         1x1                 8  double              
  a         1x1                 8  double              
  ans       1x1                 8  double
