I have to different struct arrays(In the same Matlab file), what I want is to take 1 parameter/vector from a variable in a struct array and subtract it with different parameters from another variable in another struct array, is this possible?

Here is a small part of my code:

Dist(1).name = 'Pristina' Dist(1).KM_To_Fushe_ks = 13.7 % 199-13.7 = Dist(1).KM_to_Lipjan = 8.7 % 199-8.7 = Dist(1).KM_to_Sllatina = 4.2 % 199-4.2 = Dist(1).KM_to_Hajvali = 3.5 % 199-3.5 = Dist(1).KM_to_Mitrovica = 46.9 % 199-46.9 = Dist(1).KM_to_Anija = 1.9 % 199-1.9 = EV(1).name = 'Nissan Leaf 24 kWh pack' EV(1).RangeInKM_By_Manufacturer = 199 %SUBTRACT this with parameters above: EV(1).Battery_Capacity = 21.6 EV(1).Battery_Warranty_KM = 100000 EV(1).Battery_Warrany_Year = 5 EV(1).EnginePower_Kw = 80 EV(1).EnginePower_hK = 109 EV(1).Torque_in_NewtonMeter = 254 EV(1).QuickCharging_type = 'CHAdeMO' EV(1).QuickChargingEffect_kW_DC = 50 EV(1).NormalCharging_OnBoard_kW_AC = 3.3 EV(1).Seats = 5 EV(1).Luggage_in_Liters = 370 EV(1).Consumption_Mixed_kWh_per_10km_NEDC = 1.5 EV(1).Weight_Without_Driver = 1475 EV(1).TopSpeed_KM_per_hour = 144 EV(1).Acceleration_0to100KM_per_hour = 11.5 EV(1).RangeInKM_By_Manufacturer_RANK = 10

What I want is to have the number off 199 as a vector, and substract it by all these numbers `= [13.7, 8.7, 4.2, 3.5, 46.9, 1.9]`

How to do this?

Maybe I misinterpret your question, but this seem to work:

EV(1).RangeInKM_By_Manufacturer = 199 - Dist(1).KM_To_Fushe_ks

In the line you quote in your question, you left the initialization of `KM_To_Fushe_ks`

after the difference; in short, you cannot have to vaiable assignements in the same command.
Also, if you end your lines with semi-colons you will suppress the output to the command window. Like this:

Dist(1).name = 'Pristina'; Dist(1).KM_To_Fushe_ks = 13.7; Dist(1).KM_to_Lipjan = 8.7; % Etc...

Here is one solution to my problem:

distances = [KM_to_Fushe_KS, KM_to_Lipjan]; remainingrange = arrayfun(@(s) s.RangeInKM - distances, EV, 'UniformOutput', false)

Or I could do this:

remainingrange = cell(size(EV)); for evidx = 1:numel(EV) remaingrange{evidx} = EV(evidx).RangeInKM - distances; end

**how to do subtraction inside Structure - MATLAB Answers,** 1xN Structure call Structure.result Structure(1).result=1x5 Array ,[ 1 2 3 make it a 1x7 array/vector and then probably subtraction should work. For instance, s = struct('a',[1 2 3]) creates a 1-by-1 structure, where s.a = [1 2 3]. If value is a nonscalar cell array, then s is a structure array with the same dimensions as value .

Another solution is doing is putting multiple distances in once matrix:

Example:

Towns = {'Town1', 'Town2', 'Town3', 'Town4'}; distances = [0 200 13.7 8.7; 200 0 13.3 9.3; 13.7 13.3 0 255; 8.7 9.3 255 0]; EVs = {'Nissan Leaf 24 kWh pack', 'Nissan Leaf 30 kWh pack'}; ranges = [199 250];

And then I can calculate distances as a 3D matrix:

remainingrange = permute(ranges, [1 3 2]) - distances; remainingrange = bsxfun(@minus, permute(ranges, [1 3 2]), distances);

If I want to check if a EV has not enough range in KM, I could write:

tooFarForMyEV = find(remainingrange < 0) [from, to, ev] = ind2sub(size(remainingrange), tooFarForMyEV); lackingrange = table(Towns(from)', Towns(to)', EVs(ev)', remainingrange(tooFarForMyEV), 'VariableNames', {'From', 'To', 'EV', 'Deficit'})

- Ok, so It was that simple in that way i just had to create a new variable: Remaining_Range_in_KM = EV(1).RangeInKM_By_Manufacturer - Dist(1).KM_To_Fushe_ks And then it creates a new array called "Remaining_Range_in_KM", so now I just need to figure out how I can get all distances.
