create a loop/ switch elements

hello everybody, I need to create a loop, for repeat the sum in the 'if'. And I need to reassign the same element at traci.trafficlights.setPhaseDuration like switch from the same element. Thanks

if i==t(v)+(greentime(1,v) 
    traci.trafficlights.setPhase('B1', 1)
    traci.trafficlights.setPhaseDuration('B1', greentime(2,v))
end
end
if i==t(v)+(greentime(3,v)
    traci.trafficlights.setPhase('B2', 1)
    traci.trafficlights.setPhaseDuration('B2', greentime(4,v))
end
end
if i==t(v)+(greentime(1,v)+ (greentime(2,v)
    traci.trafficlights.setPhase('B1', 0)
    traci.trafficlights.setPhaseDuration('B1', greentime(1,v))
end
end
if i==t(v)+(greentime(3,v)+greentime(4,v)
    traci.trafficlights.setPhase('B2', 0)
    traci.trafficlights.setPhaseDuration('B2', greentime(3,v))
end
end
if i==t(v)+(greentime(1,v)+ (greentime(2,v)+(greentime(1,v)
    traci.trafficlights.setPhase('B1', 1)
    traci.trafficlights.setPhaseDuration('B1', greentime(2,v))
end
end
if i==t(v)+(greentime(3,v)+greentime(4,v)+(greentime(3,v)
    traci.trafficlights.setPhase('B2', 1)
    traci.trafficlights.setPhaseDuration('B2', greentime(4,v))
end
end

... and repeat this 'sum' until i reach a contition (for example T<90)

[Benjamin Thompson]

You can use the while keword to create loop that continues until T >= 90. To provide a better answer we need more information. I do not see any use of "sum" in your pseudocode. Can you try to code this up in MATLAB and then ask more specific questions and post your code?

The code cannot run due to missing closing parentheses:

if i==t(v)+(greentime(1,v) 
%          ^              ^ ???
