包括输入y=(exp(x^3)-1)/(1-cos(sqrt(x-sin(x))))也出现?Error using ==> mpower
Matrix must be square.

y=(exp(x.^3)-1)./(1-cos(sqrt(x-sin(x))))
加2个点就可以了.这个是点对点运算.(.^和./)

用matlab求导复合函数求下列函数的一、二阶导数:(1) y=log(f(x)); (2) y=f(exp(x))+exp(f(x)) 用Matlab里面输入公式Q = 0.4752 * exp(2.4869 - 0.0014 * x^2 - 10.4661)求解答.谢谢 用matlab把f=exp(-2|x|)进行傅立叶变换, MATLAB输入f=exp((-x)^2)为什么显示?Error using ==> mpower Matrix must be square.包括输入y=(exp(x^3)-1)/(1-cos(sqrt(x-sin(x))))也出现?Error using ==> mpowerMatrix must be square. matlab中语句f=@(x,y)exp(-x.^2/3).*sin(x.^2+2*y)中@(x, 用matlab求f(x,y)=exp(2*x)*(x+y^2+2*y)的极值 z =-4*cos(2*exp(-x))*exp(-x)^2-2*sin(2*exp(-x))*exp(-x)要将x=3代入,怎样通过matlab软件实现? 用matlab怎么画图,比如y =exp(x^2)? MATLAB符号变量定义>> F=[2*x(1)-x(2)-exp(-x(1)),-x(1)+2*x(2)-exp(-x(2))]Undefined function or method 'x' for input arguments of type 'double'.>> syms x;>> F=[2*x(1)-x(2)-exp(-x(1)),-x(1)+2*x(2)-exp(-x(2))]Index exceeds matrix dimensions.怎么 假如有一个隐函数2x+lnx/y=exp(y),其中x是一个可输入的变数值,用MATLAB求y 值怎么求 matlab 中高斯函数的求值问题!函数如下f(x)=71.99*exp(-((x-7.05)/2.407)^2) + 218.6*exp(-((x-6.571)/0.5341)^2) +77.01*exp(-((x-20.73)/ 0.5899)^2) + 38.57*exp(-((x-17.14)/ 1.025)^2) + 102.3*exp(-((x-19.47)/ 1.225)^2) x是一个数组,求y值 matlab中 syms x; t=1+X-1/X; Y=exp(x+1/x); f=t*y; int(f,x,1/2,2); matlab exp(x)=1+x+x^2/2!用matlab编 在matlab中输入z1=2*sin(85)/(1+exp^2)会显示错误信息,怎样输入才是正确的? 请高手求解MATLAB 方程组想求下面的方程组,用MATLAB怎么求啊?352.1775*exp(a+b*x)+190.6011*exp(a+b*x+c*x^2)+182.2338*exp(a+b*x+c*x^2+d*x^3)+218.8316*exp(a+b*x+c*x^2+d*x^3+e*x^4)+153.3209*exp(a+b*x+c*x^2+d*x^3+e*x^4+f*x^5)=219.4330(2.2 求助用matlab画出一个函数的等高线f(x1,x2)=exp(x1+3*x2-0.1) + exp(x1-3*x2-0.1) + exp(-x1 - 0.1)我的程序是这样的:[X,Y] = meshgrid((-10:1:10),(-10:1:10));Z = exp(X+3.*Y-0.1)+exp(X-3.*Y-0.1)+exp(-X-0.1);%Z = X.*exp(-X.^2-Y.^2);[C,h] function f=fun_es(x); f=0.5*exp^(x./3)-x.*x.*sin(x); end编写一个函数M文件fun_es(x),计算如下函数其中的变量可以为标量,也可以为向量(数组)在MATLAB里输入如下指令检验此函数 fun_es(3) fun_es([1 2 3 4])请问 用MATLAB怎么绘出f(x)=exp(-x^2)*(x+sin(x))x在-10到10之间怎么没有图像呢?
