how to do subtraction inside Structure

1xN Structure call Structure.result Structure(1).result=1x5 Array ,[ 1 2 3 4 5]

Structure(2).result=1x7 Array,[1 2 3 4 5 6 7]

How to do Structure(2).result -Structure(1).result

I mean Every element inside Structure(2) - every structure inside Structure(1)

I tried

Structure(2).result(1:7) - Structure(1).result(1:5)

But it won't work.

Is it a must to write a loop? like

for i=1:5
Structure(2).result(1:7) - Structure(1).result(i)
end

Actually, what I want to do is that

1xN Structure call Structure.result

for i= 1:N

Structure(i).result=1x5 Array ,[ 1 2 3 4 5]

I want to find every array contained inside the structure - every array there EG (Structure(1).result=1x5 Array ,[ 1 2 3 4 5]-

Structure(i).result=1x7 Array,[1 2 3 4 5 6 7]) 
and find the any number == 10;
if number =10

combine Struct(1)and Struct (2)into New structure

and use the New struct to do the substraction

Edit

a=struct('result',{1:5,1:7})
b=struct('result',num2cell(bsxfun(@minus,a(1).result',a(2).result)))

Thank you so much.You are really good at matlab.

Well Technically its not possible. You are trying to subtract 1x5 from 1x7 array, which is violation of dimensionality. As a workaround, what you can do is the idea of padding dummy numbers like zeros to 1x5 and make it a 1x7 array/vector and then probably subtraction should work. I hope this helps.

Please let me know in case of further doubts.

How to pad with zeros?

[Pratik Bajaria]

Although, solution posted above seems working (by Azzi Abdelmalek), which is Great. Here's what i would have done to the most basic level.

1. Get the size of biggest array from the given structure. 2. Pad the deficit zeros using 'zeros(x,y)' command in MATLAB. 3. Make them all in Unison w.r.t. dimensions. 4. Subtract.

Although, this idea seems more like a workaround, the one posted by Azzi Abdelmalek seems Great!

Anyways, Result matters. Even i got to learn something new.

Patrick, padding with zeros is not what Tabw is asking for, and our solutions are completely different.
