Enforcing a rule in a symbolic expression in Matlab -


i have asked same question in matlab user community.

i have following symbolic expression:

(3*s11)/2 + (3*s12)/2 + (3*s13)/2 + (3*s14)/2 + (3*s15)/2 + (s11*s12)/2 + (s11*s13)/2 + (s11*s14)/2 + (s12*s13)/2 + (s11*s15)/2 + (s12*s14)/2 + (s12*s15)/2 + (s13*s14)/2 + (s13*s15)/2 + (s14*s15)/2 + s11^2/4 + s12^2/4 + s13^2/4 + s14^2/4 + s15^2/4 + 9/4

it stored symbolic expression variable. enforce rule sij^2 = 1 i.e. variables can either -1 or +1. if enforce rule in expression mentioned above, expression follows.

(3*s11)/2 + (3*s12)/2 + (3*s13)/2 + (3*s14)/2 + (3*s15)/2 + (s11*s12)/2 + (s11*s13)/2 + (s11*s14)/2 + (s12*s13)/2 + (s11*s15)/2 + (s12*s14)/2 + (s12*s15)/2 + (s13*s14)/2 + (s13*s15)/2 + (s14*s15)/2 + 1/4 + 1/4 + 1/4 + 1/4 + 1/4 + 9/4

how can in matlab?

set assumptions e.g. assume(s14^2==1), use simplify.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
