[求助]关于怎样求解代数方程(敬请帮忙,先谢过了)

soul27

有一个代数方程,阶次不定,但是含有两个未知数,应该怎样求解?<BR>不知道matlab里有没有专门解法,<BR>如果没有就要编程求解,<BR>二维搜索不是很熟,<BR>一维的可以用二分法,二维的应该也可以,但是没有思路,给点建议吧<BR>

please check the "solve" fuction in the matlab help to solve noliner <br>simultaneous equations .The basic form is <br>                   [t,y]=solve('Function name',[the solution domain],innitial value]

我举个例子<BR><BR>要求数值解：x^6*y^5*4+x^3*(y+1)-x^2*y^3*3-12=0<BR><BR>x=?<BR>y=?<BR><BR>主任帮忙啊

<P>To one's surprise, the equation you proposed consists two variables will resut in <BR>indefinite solutions.<BR><BR>For example,[u,v] = solve('a*u^2 + v^2 = 0','u - v = 1') regards 'a' as a<BR>       parameter and solves the two equations for u and v.</P>
