Plot 为什么Mathematica显示一个空白框？
我正试图画出Mathematica的函数。但它显示了一个空白框Plot 为什么Mathematica显示一个空白框？,plot,wolfram-mathematica,Plot,Wolfram Mathematica,我正试图画出Mathematica的函数。但它显示了一个空白框 \[Lambda] = -2.5*I; e0 = .5; w = .04; a1 = sqrt[e0^2 - 4*\[Lambda]^2]*(x + t/(4*\[Lambda]^2 - w^2)); h = e0 - 4*I*\[Lambda]*((e0*Sinh[a1] - 2*I*\[Lambda])/(2*I*\[Lambda]*Sinh[a1] + e0)); Plot3D[Abs[h], {x, -2, 2}, {t,
