请问如何用matlab计算下列线性方程组?
方法一:X=A\\B 矩阵除法 A=[2 1 1;3 1 2;1 2 2];B=[4;0;3];X=A\\B 方法二:X=inv(A)*B 逆矩阵法 X=inv(A)*B 运行上述代码,可以得到该线性方程组的解。方法三:用solve 函数,也解三元一次方程组。
再向你问一下用matlab借下面这个方程组,代码怎么写?感激不尽?
代码如下:f=@(x)([x(1)-sqrt((x(2)-5.764)^2+(x(3)-0.648)^2)-5.8003;x(1)-sqrt((x(2)-6.286)^2+(x(3)-1.202)^2)-6.3999;x(1)-sqrt((x(2)-6.759)^2+(x(3)-1.832)^2)-7.0031]);x=fsolve(f,[7.0031 6.759 1.832])结果如下:x = 9.7490 ...

用matlab解下列方程组(含积分)
从原理上说,Tx、Ty应该可以是随时间变化的函数,但那样就成了一个泛函问题。如果Tx、Ty取常数值方程有解,而且没有其它要求,当然应该使用常数解。现在假设Tx、Ty为常数,可以使用fsolve求解:m = 2400;Q = 7500\/2490;a = 1.63;% Tx = x1, Ty = x2, t = x3f = @(x) [quadl(@(t)...
如何用MATLAB求解方程组?
用MATLAB求解方程:两个步,一个注意。第一步:使用“syms”定义变量;第二步:使用“solve”函数求解方程;注意:函数表达时,用“==”;比如x+y==5(而不是x+y=5);举例:syms x y z ;(有几个变量就定义几个)solve(方程1,方程2 ,方程3,x,y,z)

用matlab求解非线性方程组,应优先考虑vpasolve函数或solve函数,然后再考虑其他数值分析的求解方法(如牛顿法)。对于本例,可以这样求解syms x y z[x,y,z]=vpasolve(10000-100*x+1000*y-z*(100-(x*z-2000)\/100+10*y)==0,10*x-(x*z-2000)\/10-y==0,40-x+5*y+x*z\/(1000-(x*z...
