The Spider
The spider is intended to be a complete object orientated environment for machine learning in Matlab. Aside from easy use of base learning algorithms, algorithms can be plugged together and can be compared with, e.g model selection, statistical tests and visual plots. This gives all the power of objects (reusability, plug together, share code) but also all the power of Matlab for machine learning research.

我有更好的答案
solve()函数求精确解&&&double(solve('x^4-3*x^3+5*x-2=0'))ans&=2.0000&1.8019&+&0.0000i-1.2470&+&0.0000i0.4450&-&0.0000i表示实数解x=2，还有三个复数解
采纳率：91%
来自团队：
用MATLAB求x^4-3x^3+5x-2=0方程的解，可以用下列方法来实现：1、用vpasolve（）函数命令syms x,x=vpasolve(x^4-3*x^3+5*x-2)2、用roots（）函数命令p=[1 -3 0 5 -2]; & %方程的系数roots(p)执行结果其他方法，如fsolve，fzero，数值迭代法（二分法，牛顿法）只能得到某一数值。

这是高一的数学考试题。没有人有人敢回答案。
f(x)=2x^5-4x^3+3x^2-5x+1=x(2x^4-4x^2+3x-5)+1=x(x(2x^3-4x+3)-5)+1=x(x(x(2x^2-4)+3)-5)+1。。。
