参考In mathematics,arg max(orargmax)stands for the argument of the maximum ,that is to say ,the value of the given argument for which the value of the given expression attainsits maximum value:
argmaxf(x)=> {x|任意y(y!=x=> f(y)<f(x))}
即argmaxf(x)返回的是f(x)取最大值时所对应的x的值
用符号积试了一下:
fcc=3.12;
tcc=350;
c=sym('c');
t=sym('t');
x=sym('cos(t)');
g=(2*pi*c^2)^(1/4).*exp(((t-tcc).^2)/(4*c^2)).*exp(j*m0/2*(t-tcc).^2+j*fcc*(t-tcc));
neiji_xg=int(x*g,t,1,length(t));
1.请问用这种符号积分INT可以表示它的内积吗?
2.可以对一复数求积分吗?
3.运行了一下之后还出现Warning: Explicit integral could not be found,
这会是什么原因导致的呢?
