I have an expression involving 2 bessel functions and no matter what I do I cannot get it to plot the expression. The bessel_y and the bessel_j functions are both in the expression and so is %i so I just want the realpart.
I have tried this.
set_plot_option([plot_realpart,true]);
plot2d(-(%i/2+sqrt(3)/2)*%i*'(bessel_y(1/6,-x^3/3))+(bessel_j(1/6,-x^3/3))*sqrt(x),[x,.001,2],[plot_format,gnuplot]),orthopoly_returns_intervals : false;
and I have tried this
plot2d(-(%i/2+sqrt(3)/2)*%i*'(bessel_y(1/6,-x^3/3))+'(bessel_j(1/6,-x^3/3))*sqrt(x),[x,.001,2],[plot_format,gnuplot]),orthopoly_returns_intervals : false;
and this
plot2d(-(%i/2+sqrt(3)/2)*%i*(('bessel_y(1/6,-x^3/3)+'bessel_j(1/6,-x^3/3)))*sqrt(x),[x,.001,2],[plot_format,gnuplot]),orthopoly_returns_intervals : false;
Does anyone know what I am not doing right? Non of the above work, I get no plot window.
Thanks,
Rich
