matlab如何求含e的x的平方的方程-254.58348 + (67668.47508/(152.02804*sqrt(pi/2)))*exp(-2*((x-44.21377)/152.02804)^2)=5.037*x+2.04819
用solve函数:
syms x
solve('-254.58348 + (67668.47508/(152.02804*sqrt(pi/2)))*exp(-2*((x-44.21377)/152.02804)^2)=5.037*x+2.04819','x')
得到结果:
ans =
14.305956536011014178513259586977
用solve()函数就可以解决。
x=solve('-254.58348 + (67668.47508/(152.02804*sqrt(pi/2)))*exp(-2*((x-44.21377)/152.02804)^2)=5.037*x+2.04819')
x =
14.305956536011014178513259586978
验证:
x=14.305...
