Hello, I am trying to do the following in Mahtematica 3.0.0 for Linux
BB[I_,a_,NN,d_,z_]= (I*NN/(2*d))*(z/Sqrt[a^2+z^2])
Plot[BB[1,0.05,100,0.01,z],{z,-1,1}]
Instead of getting the plot, I get the following error message:
Plot::"plnr":
BB[1,0.05,100,0.01,z] ] is not a machine-size real number at z = -1 ..
Plot::"plnr":
BB[1,0.05,100,0.01,z] ] is not a machine-size real number at z =
-0.918866
Plot::"plnr":
BB[1,0.05,100,0.01,z] ] is not a machine-size real number at z =
-0.830382 ..
General::"stop":
Further output of Plot::"plnr" will be suppressed during this
calculation.
---------------------------------------------------
What does this mean? Is the definition of my function incorrect?
Thank you very much in advance
