Mar7 asked How to add a subplot in corner of plot? Feb1 awarded Popular Question Dec11 awarded Notable Question Nov8 comment Plotting a function only non-zero for discrete values of argument Thanks a lot. Is there an easy way to then build $f(E)$ from this table of pairs? i.e. for each row: compute $E$ and then compute $f(E)$ by adding the $w$ functions from the summand for each $(n,\ell)$ pair in the row... Nov8 accepted Plotting a function only non-zero for discrete values of argument Nov6 comment Plotting a function only non-zero for discrete values of argument Upper limits of the sums are infinity, but I don't need to calculate f for an E corresponding to such high values, so in principle the cut-off is arbitrary, depending on the range of the plot one wishes to generate. I don't think it is necessary to know the values of the constants, but an example is $\rho=0.5,R=1000$ Nov6 comment Plotting a function only non-zero for discrete values of argument Included code now.
