求教exp(x)*exp(x)'的定积分如何求得?

如何用matlab求这个定积分? matlab求一个定积分解析解 matlab计算定积分 matlab 计算定积分, matlab 定积分 matlab求定积分报错The integrand function must return an output vector of the same length as the i>> df=@(x)exp(x)*(exp(x))'df = @(x)exp(x)*(exp(x))'>> quad(df,0,1)Error using quad (line 75)The integrand function must return an output vector of matlab求定积分求定积分,积分te的负t次dt,积分区域在-3到-4. 在matlab中怎样求带有参数的定积分 怎样用matlab求上下限含字母定积分 怎么用matlab求含字母的定积分?比如： 用matlab计算定积分 matlab求xlnx从1到e的定积分为什么我求出来总是错的 如何用matlab做sqrt(1-x^2)*x*log(2+x)的数值积分定积分，区间是-1到1，用quad函数，怎么着都做不对各种报错 matlab中用复化梯形公式求积分一直报错> S=FSimpson(@f,0,1,8)?Error:"f" was previously used as a variable,conflicting with its use here as the name of a function. 编写一个求定积分的函数,功能如下：已知一个函数表达式、积分上限、积分下限,返回定积分.用MATLAB! 定积分定义 求积分 定积分,对0求定积分 matlab能计算定积分吗?
