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 matlab编程中 出现Matrix must be square.怎么办?Q=0.11;g=9800;gamma=4.8*10^-5;rho=1.109*10^-6;H=9;d=1;u0=4*Q/(pi*d^2);syms rsy=H-(u0^2/(2*g))*(d^4./(16*rs.^4)-1)-4*gamma*(d./(2*rs)-1)/(d*g*rho); R1=diff(y);%y对r（s）求一阶偏导 R2=diff(y 在matlab编程中,for i=1:m什么意思? Matlab中出现? Error using ==> mtimes Inner matrix dimensions must agree. 是什么意思啊,程序如下pd=0.95;pfa=10e-8;N=10:10:100;m=6.79*(1+0.253*pd)*(1+(log10(1/pfa))/46.6)*(1-0.14*log10(N)+0.0183*log10(N)*log10(N))plot(N,m) 怎么样才 matlab出现Matrix is close to singular or badly scaled是怎么回事? matlab 如何求矩阵中NaN所在的位置 [m n]=find(a==NaN)命令后显示Empty matrix:为什么 matlab 如何求矩阵中某个数所在的位置 [m n]=find(a==max)命令后显示Empty matrix:为什么 One or more output arguments not assigned during call to在matlab中编程会出现这句话, Matlab中出现Error using ==> *Inner matrix dimensions must agree.程序如下：m=0:pi/50:2*pi;n=0:pi/50:pi;hold onNo=150;xn=1000*rand(No,1);yn=1000*rand(No,1);zn=1000*rand(No,1);v=109.88;t=-1;while t Matlab中Inner matrix dimensions must agree.>> clear>> Ts=10*10^(-6);M=4;f0=5*10^6;B=30*10^6;>> fs=300*1/Ts/10;>> t=[0:1:100];>> if 0 U=B/Ts;>> S1=u*exp(f0*t+0.5*U*t*t);就到这一步出现上面的问题. MATLAB 中已知a1=1;a2=2;a3=3;a4=4 b1=4;b2=3;b3=2;b4=1;怎么求 s(i)=a(i)+b(i)(i=1:4) 如：s1=a1+b1用eval函数：m=1:4eval(['s' num2str(m)])=eval(['a' num2str(m)])+eval(['b' num2str(m)])就会出现Index exceeds matrix dimensions.要不就是 Co matlab中n=m(:,:,感觉m是二维矩阵,怎么会出现m（：,：,i）呢? 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. Matlab中出现?Error using ==> mtimes Inner matrix dimensions must agree.程序如下x=3:0.1:20;y=x*(cos(x))^3.*(sin(x))^2+x^2.*(sin(x*8))^3-9*x^4.*cos(x); MATLAB程序,这个程序不知道为什么出现?Error using ==> mpower Matrix must be square. matlab中出现了这个问题, 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? 请教matlab中矩阵某元素个数的编程问题
