# RGTensor (Mathematica package) Print and Plot3D functions [closed]

I plot a function for a spherically symmetric metric in RGTensor package written for Mathematica and for pressure profile I obtain a complicated plot.

But then as I Print[] the corresponding pressure profile the value is zero which contradicts the resultant plot. Does anyone know why this happens?

• There is no contradiction. The plot is essentially the zero-function - have a look at the axes. – AccidentalFourierTransform May 12 '17 at 17:36

This is essentially impossible to answer conclusively without more context, but unless you actually intended to plot a quantity that was of the order of a few times $10^{-16}$ (which is roughly where the machine-error threshold normally sits), then your plot is essentially the zero function, and there is no contradiction there.
