原函数不存在的积分画图的问题刚刚学习matlab,还请各位不吝赐教:已知函数 f(x)=exp(x^2+sqrt(2*sin(k*x)^2+1)),k 为给定常数1,2,3,4,其原函数为:F(x)=int(f(x),x)但是用int得不到F(x)的解析表达式,所以我
怎么用matlab解这个方程,急用,-263671.875/((1.875*t+3)^3)+800*sqrt(5)*(1-exp(-2*t*sqrt(0.05)))*exp(-2t*sqrt(0.05))/((1+exp(-2*t*sqrt(0.05)))^3)
问一个Matlab小问题两个m文件function [Q]=Q(x);syms u;Q=(1/sqrt(2*pi))*int(exp(-u^2/2),x,inf);x=-6:0.1:20;y=Q(x);为什么有错误?
maple求二重定积分,x,y积分变量,d,r参数,为什么得不到结果,还是留一个积分?int(int(exp(-(x^2+y^2)/(2*50*50)),y = -sqrt(r^2+(x-100+d)^2) ..sqrt(r^2+(x-100+d)^2)),x = 100-d-r ..100-d)
matlab绘制隐函数图象char a b f;syms x y f=exp((1/(5*sqrt(2*pi)))*exp(-(y-100)^2/50));ezplot('int(int(f,y,0,969600*b-(20*a+20)*(2000-x)),x,500,2000)=500')
matlab上这个函数怎么老提示错误?Yz1=t/t0*(u^2+(1-u^2-(3/(4*u^2)))*(2/sqrt(pi))*int(exp(-t^2),t,0,u)+t/(2*sqrt(pi)*t0)*(3/(2*u)-u)*exp(-u^2)
