matlab解方程怎么出错了[x,y,z]=('x^2-5*y^2+7*z^2+12=0 ','3*x*y+x*z-11*x=0','2*y*z+40*x=0') matlab解方程中solve('cos(t)=(0.05913+57.*sin(t))/(0.0976*57+t*57)','t')出错了 matlab里面 请问f=@(x,y,z)(1+y)*z.^y-(-0.25*(x-1)^2+0.25)^x.; 一直出错. Matlab 出错 matlab出错, MATLAB解方程出错>> z=solve('(10-10*(200i+x))/100=10+10*(200i+x)/(-50i)','x')Error using ==> solve' (10-10*(200i+x))/100=10+10*(200i+x)/(-50i) ' is not a valid expression or equation. matlab 极小化函数f（x,y) = -9*y - 10*z + 100*(-1*log(100-y-z)) - log(y) - log(z) - log(50-y+z)matlab怎么极小化这个函数,我搞的老是出错 matlab程序如下,不知道哪出错了x=1:10;z=asin(sin(x)./1.468);plot(x.z); matlab解方程,x+2y+z=1 2x+y-2z=3 3x-4y+2z=9 利用matlab 计算四杆机构通过方程matlab计算,假设AD=BC=600mm,AB=200mm(AB+BC)^2=AD^2+CD^2-2AD*CD*COSa(BC-AB)^2=AD^2+CD^2-2*AD*CD*COSba-b=60求AB和CD的长度.分别列出a,b角度和CD杆长度的各个计算数值.参考：[a,b,CD]=solv 求用matlab解如下微分方程的方法本人菜鸟,求用matlab解如下方程的方法：dy/dx=f（x,y,z）dz/dx=g(x,y,z)求此方程数值解 各位高人看下下面用MATLAB计算的的方程哪出错了[x y z w]=solve('x*cos(y)=125*cos(pi/3)','x*sin(y)=275+125*sin(pi/3）','600*cos(y)+150*cos（z）-w=0','600*sin(y)+150*sin（z）=300','x,y,z,w')Error using solve>getEqns (line 292)' x*s matlab 求和的出错 matlab 解非线性方程组'tan(a)-h/l=0','tan(b)-x(i)/(high-sumh(i)-ha)=0','sin(a+b)/sin(a)-1.3333=0','ha-(0.778*tan(a)^4+1-(1-0.778*tan(a)^2)^1.5/1.333)*high*cos(a)/((tan(a)^2+1)^0.5)=0','a','b','h','ha' 四个未知数其他变量已给出用solv 以下是matlab中的语句,syms t y=sin(pi*t)*exp(-s.*t) z=int(y,t,0,1) 求指导哪里出错了? 用matlab解微分方程组：dy/dz – z =cosx,dz/dx + y =1 .>> [x,y,z]=dsolve('Dy-z*Dz=cos(x)*Dz,Dz+y*Dx=Dx')Error using ==> dsolveToo many output arguments.Error in ==> dsolve我就这么按照老师教学PPT的一道题模拟的,但是出错了~ |z|=1解方程z^5+z=1 解方程:z^2=Z.(其中z是复数)
