matlab出现Matrix is close to singular or badly scaled是怎么回事?

matlab出现Matrix is close to singular or badly scaled是怎么回事? MATLAB程序,这个程序不知道为什么出现?Error using ==> mpower Matrix must be square. matlab Matrix must be square什么情况?A为一个1119*2的数组当我输入A1=inv（A）时出现matlab Matrix must be square 为什么啊? Matlab计算Index exceeds matrix dimensions.为什么?... MATLAB矩阵min已知matrix是一个二维矩阵,请问大虾：matrix=min(matrix,matrix.');是什么含义 matrix 请问如何在matlab中画函数图形 r=cosh(t)*exp(-t/100) 为什么会出现 Inner matrix dimensions must agree.如何画 程序代码 What is the Matrix?Matrix都有什么涵义? matlab中绘制三维图形时,z [x,y] = meshgrid(0:0.01:1);z=x+y;if x=0.5z = x-3*x-y+x.*y;end mesh(x,y,z);如上,if else 不起作用,而我需要利用一个包含多个判断语句的函数计算z.另外执行时会出现Warning:Matrix is singular matlab中计算结果出现NAN是什么意思a=[1 -1 -2 -1;2 1 1 1;1 1 0 -3;0 1 -1 -7],b=[0;0;0;0],c=aa = 1 -1 -2 -1 2 1 1 1 1 1 0 -3 0 1 -1 -7b = 0 0 0 0Warning: Matrix is matlab求10阶线性方程出现Warning:Matrix is singular to working precision.怎么破?clear;A=[1.75,0.75,-1,0,0,0,0,0,-0.75,-0.75;0.75,0.75,0,0,0,0,0,0,-0.75,-0.75;-1,0,1.75,-0.75,-1,0,-0.75,-0.75,-0.75,0.75;0,0,-0.75,0.75,0,0,-0.75,-0.75,0.75,-0 Matlab 高斯-赛德尔迭代法怎么用呢?（关键是怎么调用它,附代码）function X=gseid(A,B,P,delta,max1)% Input - A is an N x N nonsingular matrix% - B is an N x 1 matrix% - P is an N x 1 matrix; the initial guess% - delta is the toler adams仿真重制失败是什么原因我做整车模型仿真是出现下面信息：WARNING:The symbolic refactorization failed.The matrix is structurally singularat time = 3.1991.WARNING:The symbolic refactorization failed.The matrix is structural matlab函数输入y=1/(1+x^4)这个函数在MATLAB里面到底怎么输入才对?按照上面的输入的话就会出现Error using ==> ^Matrix must be square. 英语翻译now dispersion is unit matrix这是在matlab一个程序里的一句注解,我不懂那个dispersion怎么翻译? What is the Matrix?该怎么回答 Matlab出现Inner matrix dimensions must agree问题x=linspace(0,2*pi,30);y=sin(x)*cos(x);plot(x,y)点回车就出现：? Error using ==> mtimesInner matrix dimensions must agree.这是怎么回事?怎么解决? x=4*sin(2*pi*0.01*t).*sin(2*pi*3*t)+2*cos(pi*t*t/4);在matlab中怎样表达运行出现错误：Error using ==> mtimesInner matrix dimensions must agree.
