MATLAB中,x=linspace(0,2*pi,

x=linspace(0,2*pi)在matlab中是什么意思 MATLAB中,x=linspace(0,2*pi, matlab中t=linspace(0,2*pi,100);x=[t;t]';y=[sin(t);cos(t)]';plot(x,y), MATLAB的问题x=linspace(-5,5);if x>=0;y=sqrt(x)if x syms a x y x=sin(a) y=cosh(x) a=linspace(0,2*pi) plot(a,y) 错误在哪里?matlab中，错误提示：Conversion to double from sym is not possible matlab画图不输出图形linspace(0,1500,150000);y=[];syms x;x=x+0;for x=1:1500;if x matlab >> syms x y;x=linspace(0,2*pi,60);y=(sin(x)*cos(5*x));plot(x,y) 无法出图, 关于matlab中绘制3维图像中[x,y]=meshgrid(x,y);与[xx,yy]=meshgrid(x,y);的区别,谁知道 告诉下x=linspace(-5,5,20);y=linspace(0,10,30);[x,y]=meshgrid(x,y);z=cos(x).*cos(y)*.exp((-1/4)*sqrt(x.*x+y.*y))meshc(x,y,z);代码这样就不行, matlab linspace,为什么我输入linspace(0,1,5.5)和linspace(0,1,5)输出结果一样? MATLAB meshgrid x=1:4y=linspace(1,2,2)[X,Y]=meshgrid(x,y） matlab中用mesh画函数时公式里有正负号怎么在一个图形里显示出来?公式如下图所示,我想用MATLAB软件画图,命令：>> l=160;x=linspace(0,80,50);y=linspace(-80,80,50);[X,Y]=meshgrid(x,y);Z=meshgrid((0.2.*exp(-0.0221 matlab surf用法xgrid=linspace(0,100,10000);ygrid=linspace(0,100,10000);[x,y]=meshgrid(xgrid,ygrid);z=(3236*x.^2*y+1109*x.^2+5416*x*y.^2+6616*x*y+1445*x+2199*y.^2+1990*y+318)./[1000*(2*x+1)*(2*y+1)*(x+y+1)];surf(x,y,z); matlab的rotate语句出错,figure(2)colormap('flag');n=100;x=linspace(-3,3,n);y=linspace(-3,3,n);z=linspace(-3,3,n);[X,Y,Z]=ndgrid(x,y,z);F=(X.^2+(9/4) .* (Y.^2)+Z.^2-1).^3-X.^2 .* Z.^3-(1/9) .* Y.^2 .* Z.^3isosurface(F,0)axis equalview([55 34]);tit matlab仿真老是出现错误,请问怎么改?clear;clc;deta=2;w=2.5;theta=0;a=linspace(-10,10,25);b=linspace(-1.0,1.0,25);[x,y]=meshgrid(a,b);s(x,y)=exp(-0.5*((x/deta)^2+(y/deta)^2)).*sin(w*(x*cos(theta)+y*sin(theta)));plot3(x,y,s(x,y)); Subscript 如何用matlab画y=x/(1-x)这个函数图 我用的这个程序 x=linspace(0,1,200); y=(x/(1-x)); plot(y,x)这是怎么回事 求帮忙 matlab里的linspace(x,y*pi,z) 和 linspace(x:y:z) 是一个意思吗 菜鸟求助：matlab中surf函数画参数函数的z如何确定为矩阵?具体程序如下：syms alphb betab X Y Z;rE=4226;e=870;alphb=linspace(-pi/6,pi/6,11);betab=linspace(-pi/8,pi/4,10);[Ab,Bb]=meshgrid(alphb,betab);x=-(rE*cos(Bb)+e).*sin(Ab); matlab二元正态分布mvnpdf中Sigma矩阵式什么意思啊?mu = [1 -1]; Sigma = [.9 .4; .4 .3];[X1,X2] = meshgrid(linspace(-1,3,25)',linspace(-3,1,25)');X = [X1(:) X2(:)];p = mvnpdf(X,mu,Sigma);surf(X1,X2,reshape(p,25,25));如果我要单单该Si
