题目matlab画图实验时出现错误,显示:Matrix must be square作x^2 x^3 x^4 x^5的图形 我输入语句:y1=x^2;y2=x^3;y3=x^4;y4=x^5; plot(x,y1,x,y2,x,y3,x,y4)按回车显示“??? Error using ==> mpower Matrix must be square.” 相关知识点: 试题来源: 解析 应该是y1=x.^2,其他也是...
百度试题 结果1 题目用MATLAB画出Logistic 模型式子:y=112.5/(1+29×e^(-0.5×x))用plot,他告诉我‘Matrix must be square ’ 相关知识点: 试题来源: 解析 syms x y, y=112.5/(1+29×exp(-0.5×x)), ezplot(y)反馈 收藏
matlab7.0中求以10为底的对数,指数为x.如x=1:1:10,求y=10^x.注意,matlab7.0中好像向量不能做指数..程序:x=1:1:10;y=10^x;结果如下:Error in ==> Untitled at 2y=10^x;Error using ==> mpowerMatrix must be square.求解决方案.
x^3就是矩阵运算，你设的x是一个行向量，自乘无法实现。要实现每一个数的计算。改成：y=x.^3+2.*x+5 多加一个"."就可以实现
对于乘法、除法、乘方等三种数组运算，应按点乘（。*）、点除（。/）、点乘方（。^）来进行运算。所以y1，y2，y3的表达式应改写为 y1=max(1,2./((x).^2+1).^0.5);y2=min(1,2./((x).^2+1).^0.5);y3=(4./((x).^2+1)).^0.25;运行结果如下 ...
把x^3改成x.^3
l=inv(p); p is a matrix of 1*20. i want to take its inverse but matlab error says ''Matrix must be square''. please tell me, what shall i do if i want to take the inverse of p. Thankyou0 Comments Sign in to comment.Sign in to answer this question.Accepted...
Matrix must be square error. q0= 1i.*k.*(-1+(Ra./k^4)^(1/3))^(1/2); q1= k.*(1+(Ra./k^4)^(1/3).*(1/2+1i*sqrt(3)/2))^(1/2); q2= k.*(1+(Ra./k^4)^(1/3).*(1/2-1i*sqrt(3)/2))^(1/2);...

clear;clc b=0:0.01:5;x=b;f=1./(((1-x.^2).^2+(2*0.5*x).^2).^0.5); % 还要加“点”plot(x,f)
