Hello, this is my attempt to create a grph of 2-D ising Modle. However, I get an error message
ListDensityPlot::nonopt: Options expected (instead of PlotRange\[RightArrow]{-1,1}) beyond position 1 in ListDensityPlot[<<1>>]. An option must be a rule or a list of rules.
I replaced the "RightArrow" to "Rule", but my Mathematica automatically change "Rule" to "Rightarrow". What should I do to resolve this issue?
Thank you!
\[Rule]would be replaced by\[RightArrow], but as an immediate workaround (and typically what I type) use-followed by>. When you enter a space afterward, the front end should replace it with\[Rule]. $\endgroup$
